Grid system

Style Guide includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts.

Introduction

Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Style Guide grid system works:

• Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
• Use rows to create horizontal groups of columns.
• Content should be placed within columns, and only columns may be immediate children of rows.
• Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
• Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
• The negative margin is why the examples below are outdented. It's so that content within grid columns is lined up with non-grid content.
• Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.
• If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
• Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any .col-md- class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg- class is not present.

Look to the examples for applying these principles to your code.

Media queries

We use the following media queries in our Less files to create the key breakpoints in our grid system.

/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Style Guide */

/* Small devices (tablets, 768px and up) */
@media (min-width: @screen-sm-min) { ... }

/* Medium devices (desktops, 992px and up) */
@media (min-width: @screen-md-min) { ... }

/* Large devices (large desktops, 1200px and up) */
@media (min-width: @screen-lg-min) { ... }

We occasionally expand on these media queries to include a max-width to limit CSS to a narrower set of devices.

@media (max-width: @screen-xs-max) { ... }
@media (min-width: @screen-sm-min) and (max-width: @screen-sm-max) { ... }
@media (min-width: @screen-md-min) and (max-width: @screen-md-max) { ... }
@media (min-width: @screen-lg-min) { ... }

Grid options

See how aspects of the Style Guide grid system work across multiple devices with a handy table.

Example: Stacked-to-horizontal

Using a single set of .col-md-* grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices. Place grid columns in any .row.

<div class="row">
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
	<div class="col-md-1">.col-md-1</div>
</div>
<div class="row">
	<div class="col-md-8">.col-md-8</div>
	<div class="col-md-4">.col-md-4</div>
</div>
<div class="row">
	<div class="col-md-4">.col-md-4</div>
	<div class="col-md-4">.col-md-4</div>
	<div class="col-md-4">.col-md-4</div>
</div>
<div class="row">
	<div class="col-md-6">.col-md-6</div>
	<div class="col-md-6">.col-md-6</div>
</div>

Example: Fluid container

Turn any fixed-width grid layout into a full-width layout by changing your outermost .container to .container-fluid.

<div class="container-fluid">
	<div class="row">
		...
	</div>
</div>

Example: Mobile and desktop

Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding .col-xs-* .col-md-* to your columns. See the example below for a better idea of how it all works.

<!-- Stack the columns on mobile by making one full-width and the other half-width -->
<div class="row">
	<div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
	<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>

<!-- Columns start at 50% wide on mobile and bump up to 33.3% wide on desktop -->
<div class="row">
	<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
	<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
	<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>

<!-- Columns are always 50% wide, on mobile and desktop -->
<div class="row">
	<div class="col-xs-6">.col-xs-6</div>
	<div class="col-xs-6">.col-xs-6</div>
</div>

Example: Mobile, tablet, desktops

Build on the previous example by creating even more dynamic and powerful layouts with tablet .col-sm-* classes.

<div class="row">
	<div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div>
	<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>
<div class="row">
	<div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
	<div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
	<!-- Optional: clear the XS cols if their content doesn't match in height -->
	<div class="clearfix visible-xs-block"></div>
	<div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
</div>

Example: Column wrapping

If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.

<div class="row">
	<div class="col-xs-9">.col-xs-9</div>
	<div class="col-xs-4">.col-xs-4<br>Since 9 + 4 = 13 &gt; 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.</div>
	<div class="col-xs-6">.col-xs-6<br>Subsequent columns continue along the new line.</div>
</div>

Responsive column resets

With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and our responsive utility classes.

<div class="row">
	<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
	<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>

	<!-- Add the extra clearfix for only the required viewport -->
	<div class="clearfix visible-xs-block"></div>

	<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
	<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
</div>

In addition to column clearing at responsive breakpoints, you may need to reset offsets, pushes, or pulls. See this in action in the grid example.

<div class="row">
	<div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
	<div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

<div class="row">
	<div class="col-sm-6 col-md-5 col-lg-6">.col-sm-6 .col-md-5 .col-lg-6</div>
	<div class="col-sm-6 col-md-5 col-md-offset-2 col-lg-6 col-lg-offset-0">.col-sm-6 .col-md-5 .col-md-offset-2 .col-lg-6 .col-lg-offset-0</div>
</div>

Offsetting columns

Move columns to the right using .col-md-offset-* classes. These classes increase the left margin of a column by * columns. For example, .col-md-offset-4 moves .col-md-4 over four columns.

<div class="row">
	<div class="col-md-4">.col-md-4</div>
	<div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
</div>
<div class="row">
	<div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
	<div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
</div>
<div class="row">
	<div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
</div>

Nesting columns

To nest your content with the default grid, add a new .row and set of .col-sm-* columns within an existing .col-sm-* column. Nested rows should include a set of columns that add up to 12 or less (it is not required that you use all 12 available columns).

<div class="row">
	<div class="col-sm-9">
	Level 1: .col-sm-9
		<div class="row">
			<div class="col-xs-8 col-sm-6">
				Level 2: .col-xs-8 .col-sm-6
			</div>
			<div class="col-xs-4 col-sm-6">
				Level 2: .col-xs-4 .col-sm-6
			</div>
		</div>
	</div>
</div>

Column ordering

Easily change the order of our built-in grid columns with .col-md-push-* and .col-md-pull-* modifier classes.

<div class="row">
	<div class="col-md-9 col-md-push-3">.col-md-9 .col-md-push-3</div>
	<div class="col-md-3 col-md-pull-9">.col-md-3 .col-md-pull-9</div>
</div>

Less mixins and variables

In addition to prebuilt grid classes for fast layouts, Style Guide includes Less variables and mixins for quickly generating your own simple, semantic layouts.

Variables

Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.

@grid-columns:              12;
@grid-gutter-width:         30px;
@grid-float-breakpoint:     768px;

Mixins

Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.

// Creates a wrapper for a series of columns
.make-row(@gutter: @grid-gutter-width) {
	// Then clear the floated columns
	.clearfix();

	@media (min-width: @screen-sm-min) {
		margin-left:  (@gutter / -2);
		margin-right: (@gutter / -2);
	}

	// Negative margin nested rows out to align the content of columns
	.row {
		margin-left:  (@gutter / -2);
		margin-right: (@gutter / -2);
	}
}

// Generate the extra small columns
.make-xs-column(@columns; @gutter: @grid-gutter-width) {
	position: relative;
	// Prevent columns from collapsing when empty
	min-height: 1px;
	// Inner gutter via padding
	padding-left:  (@gutter / 2);
	padding-right: (@gutter / 2);

	// Calculate width based on number of columns available
	@media (min-width: @grid-float-breakpoint) {
		float: left;
		width: percentage((@columns / @grid-columns));
	}
}

// Generate the small columns
.make-sm-column(@columns; @gutter: @grid-gutter-width) {
	position: relative;
	// Prevent columns from collapsing when empty
	min-height: 1px;
	// Inner gutter via padding
	padding-left:  (@gutter / 2);
	padding-right: (@gutter / 2);

	// Calculate width based on number of columns available
	@media (min-width: @screen-sm-min) {
		float: left;
		width: percentage((@columns / @grid-columns));
	}
}

// Generate the small column offsets
.make-sm-column-offset(@columns) {
	@media (min-width: @screen-sm-min) {
		margin-left: percentage((@columns / @grid-columns));
	}
}
.make-sm-column-push(@columns) {
	@media (min-width: @screen-sm-min) {
		left: percentage((@columns / @grid-columns));
	}
}
.make-sm-column-pull(@columns) {
	@media (min-width: @screen-sm-min) {
		right: percentage((@columns / @grid-columns));
	}
}

// Generate the medium columns
.make-md-column(@columns; @gutter: @grid-gutter-width) {
	position: relative;
	// Prevent columns from collapsing when empty
	min-height: 1px;
	// Inner gutter via padding
	padding-left:  (@gutter / 2);
	padding-right: (@gutter / 2);

	// Calculate width based on number of columns available
	@media (min-width: @screen-md-min) {
		float: left;
		width: percentage((@columns / @grid-columns));
	}
}

// Generate the medium column offsets
.make-md-column-offset(@columns) {
	@media (min-width: @screen-md-min) {
		margin-left: percentage((@columns / @grid-columns));
	}
}
.make-md-column-push(@columns) {
	@media (min-width: @screen-md-min) {
		left: percentage((@columns / @grid-columns));
	}
}
.make-md-column-pull(@columns) {
	@media (min-width: @screen-md-min) {
		right: percentage((@columns / @grid-columns));
	}
}

// Generate the large columns
.make-lg-column(@columns; @gutter: @grid-gutter-width) {
	position: relative;
	// Prevent columns from collapsing when empty
	min-height: 1px;
	// Inner gutter via padding
	padding-left:  (@gutter / 2);
	padding-right: (@gutter / 2);

	// Calculate width based on number of columns available
	@media (min-width: @screen-lg-min) {
		float: left;
		width: percentage((@columns / @grid-columns));
	}
}

// Generate the large column offsets
.make-lg-column-offset(@columns) {
	@media (min-width: @screen-lg-min) {
		margin-left: percentage((@columns / @grid-columns));
	}
}
.make-lg-column-push(@columns) {
	@media (min-width: @screen-lg-min) {
		left: percentage((@columns / @grid-columns));
	}
}
.make-lg-column-pull(@columns) {
	@media (min-width: @screen-lg-min) {
		right: percentage((@columns / @grid-columns));
	}
}

Example usage

You can modify the variables to your own custom values, or just use the mixins with their default values. Here's an example of using the default settings to create a two-column layout with a gap between.

.wrapper {
	.make-row();
}
.content-main {
	.make-lg-column(8);
}
.content-secondary {
	.make-lg-column(3);
	.make-lg-column-offset(1);
}

<div class="wrapper">
	<div class="content-main">...</div>
	<div class="content-secondary">...</div>
</div>

Responsive utilities

For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query. Also included are utility classes for toggling content when printed.

Try to use these on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation.

Available classes

Use a single or combination of the available classes for toggling content across viewport breakpoints.

So, for extra small (xs) screens for example, the available .visible-*-* classes are: .visible-xs-block, .visible-xs-inline, and .visible-xs-inline-block.

Print classes

Similar to the regular responsive classes, use these for toggling content for print.

Test cases

Resize your browser or load on different devices to test the responsive utility classes.

Visible on...

Green checkmarks indicate the element is visible in your current viewport.

Hidden on...

Here, green checkmarks also indicate the element is hidden in your current viewport.

Typography

Headings

All HTML headings, <h1> through <h6>, are available. .h1 through .h6 classes are also available, for when you want to match the font styling of a heading but still want your text to be displayed inline.

<h1>h1. Style Guide heading</h1>
<h2>h2. Style Guide heading</h2>
<h3>h3. Style Guide heading</h3>
<h4>h4. Style Guide heading</h4>
<h5>h5. Style Guide heading</h5>
<h6>h6. Style Guide heading</h6>

Create lighter, secondary text in any heading with a generic <small> tag or the .small class.

<h1>h1. Style Guide heading <small>Secondary text</small></h1>
<h2>h2. Style Guide heading <small>Secondary text</small></h2>
<h3>h3. Style Guide heading <small>Secondary text</small></h3>
<h4>h4. Style Guide heading <small>Secondary text</small></h4>
<h5>h5. Style Guide heading <small>Secondary text</small></h5>
<h6>h6. Style Guide heading <small>Secondary text</small></h6>

Horizontal rules

This is applied to the <hr>.

	<hr>

Body copy

Style Guide's global default font-size is 14px, with a line-height of 24px. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their computed line-height (10px by default).

<p>...</p>

Note or reference data

This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a low tone color.

<p class="text-muted">...</p>

Emphasis classes

Assign a visual meaning to the text through the use of auxiliary color.

<p class="text-primary">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
<p class="text-warning">Etiam porta sem malesuada magna mollis euismod.</p>
<p class="text-danger">Donec ullamcorper nulla non metus auctor fringilla.</p>
<p class="text-info">Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis.</p>
<p class="text-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>

Lead body copy

Make a paragraph stand out by adding .lead.

<p class="lead">...</p>

Built with Less

The typographic scale is based on two Less variables in variables.less: @font-size-base and @line-height-base. The first is the base font-size used throughout and the second is the base line-height. We use those variables and some simple math to create the margins, paddings, and line-heights of all our type and more. Customize them and Style Guide adapts.

Inline text elements

Marked text

For highlighting a run of text due to its relevance in another context, use the <mark> tag.

You can use the mark tag to <mark>highlight</mark> text.

Deleted text

For indicating blocks of text that have been deleted use the <del> tag.

<del>This line of text is meant to be treated as deleted text.</del>

Strikethrough text

For indicating blocks of text that are no longer relevant use the <s> tag.

<s>This line of text is meant to be treated as no longer accurate.</s>

Inserted text

For indicating additions to the document use the <ins> tag.

<ins>This line of text is meant to be treated as an addition to the document.</ins>

Underlined text

To underline text use the <u> tag.

<u>This line of text will render as underlined</u>

Make use of HTML's default emphasis tags with lightweight styles.

Small text

For de-emphasizing inline or blocks of text, use the <small> tag to set text at 85% the size of the parent. Heading elements receive their own font-size for nested <small> elements.

You may alternatively use an inline element with .small in place of any <small>.

<small>This line of text is meant to be treated as fine print.</small>

Bold

For emphasizing a snippet of text with a heavier font-weight.

<strong>rendered as bold text</strong>

Italics

For emphasizing a snippet of text with italics.

<em>rendered as italicized text</em>

Alignment classes

Easily realign text to components with text alignment classes.

<p class="text-left">Left aligned text.</p>
<p class="text-center">Center aligned text.</p>
<p class="text-right">Right aligned text.</p>
<p class="text-justify">Justified text.</p>
<p class="text-nowrap">No wrap text.</p>

Transformation classes

Transform text in components with text capitalization classes.

<p class="text-lowercase">Lowercased text.</p>
<p class="text-uppercase">Uppercased text.</p>
<p class="text-capitalize">Capitalized text.</p>

Abbreviations

Stylized implementation of HTML's <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a title attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover.

Basic abbreviation

For expanded text on long hover of an abbreviation, include the title attribute with the <abbr> element.

<abbr title="attribute">attr</abbr>

Initialism

Add .initialism to an abbreviation for a slightly smaller font-size.

<abbr title="HyperText Markup Language" class="initialism">HTML</abbr>

Addresses

Present contact information for the nearest ancestor or the entire body of work. Preserve formatting by ending all lines with <br>.

<address>
	<strong>Twitter, Inc.</strong><br>
	795 Folsom Ave, Suite 600<br>
	San Francisco, CA 94107<br>
	<abbr title="Phone">P:</abbr> (123) 456-7890
</address>
<address>
	<strong>Full Name</strong><br>
	<a href="mailto:#">first.last@example.com</a>
</address>

Blockquotes

For quoting blocks of content from another source within your document.

Default blockquote

Wrap <blockquote> around any HTML as the quote. For straight quotes, we recommend a <p>.

<blockquote>
	<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
</blockquote>

Blockquote options

Style and content changes for simple variations on a standard <blockquote>.

Naming a source

Add a <footer> for identifying the source. Wrap the name of the source work in <cite>.

<blockquote>
	<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
	<footer>Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>

Alternate displays

Add .blockquote-reverse for a blockquote with right-aligned content.

<blockquote class="blockquote-reverse">
	...
</blockquote>

Lists

Unordered

A list of items in which the order does not explicitly matter.

<ul>
	<li>...</li>
</ul>

Ordered

A list of items in which the order does explicitly matter.

<ol>
	<li>...</li>
</ol>

Unstyled

Remove the default list-style and left margin on list items (immediate children only). This only applies to immediate children list items, meaning you will need to add the class for any nested lists as well.

<ul class="list-unstyled">
	<li>...</li>
</ul>

Inline

Place all list items on a single line with display: inline-block; and some light padding.

<ul class="list-inline">
	<li>...</li>
</ul>

Description

A list of terms with their associated descriptions.

<dl>
	<dt>...</dt>
	<dd>...</dd>
</dl>

Horizontal description

Make terms and descriptions in <dl> line up side-by-side. Starts off stacked like default <dl>s, but when the navbar expands, so do these.

<dl class="dl-horizontal">
	<dt>...</dt>
	<dd>...</dd>
</dl>

Tables

Basic example

For basic styling—light padding and only horizontal dividers—add the base class .table to any <table>. It may seem super redundant, but given the widespread use of tables for other plugins like calendars and date pickers, we've opted to isolate our custom table styles.

<table class="table">
	...
</table>

Striped rows

Use .table-striped to add zebra-striping to any table row within the <tbody>.

<table class="table table-striped">
	...
</table>

Bordered table

Add .table-bordered for borders on all sides of the table and cells.

<table class="table table-bordered">
	...
</table>

Hover rows

Add .table-hover to enable a hover state on table rows within a <tbody>.

<table class="table table-hover">
	...
</table>

Condensed table

Add .table-condensed to make tables more compact by cutting cell padding in half.

<table class="table table-condensed">
	...
</table>

Contextual classes

Use contextual classes to color table rows or individual cells.

<!-- On rows -->
<tr class="active">...</tr>
<tr class="success">...</tr>
<tr class="warning">...</tr>
<tr class="danger">...</tr>
<tr class="info">...</tr>

<!-- On cells (`td` or `th`) -->
<tr>
	<td class="active">...</td>
	<td class="success">...</td>
	<td class="warning">...</td>
	<td class="danger">...</td>
	<td class="info">...</td>
</tr>

Responsive tables

Create responsive tables by wrapping any .table in .table-responsive to make them scroll horizontally on small devices (under 768px). When viewing on anything larger than 768px wide, you will not see any difference in these tables.

@-moz-document url-prefix() {
	fieldset { display: table-cell; }
}

<div class="table-responsive">
	<table class="table">
		...
	</table>
</div>

Layout-fixed tables

Sets the CSS attribute "table-layout" to the value "fixed".

<div class="table-responsive">
	<table class="table table-layout-fixed">
		...
	</table>
</div>

Ellipsis cells

Gives the "ellipsis" property to the td and the p elements of the table, when it's contents are longer than the width of the cell.

In the first examble below, all of the table cells have the "ellipsis" attribute.

In the second one, just the cell with the class "cell-ellipsis" has the attribute. In this case, the table must have the class "table-layout-fixed", otherwise it will not work properly.

<div class="table-responsive">
	<table class="table table-ellipsis">
		<tr>
			<td></td>
			<td></td>
			<td></td>
			<td></td>
		</tr>
	</table>
</div>

<div class="table-responsive">
	<table class="table table-layout-fixed">
		<tr>
			<td class="cell-ellipsis"></td>
			<td></td>
			<td></td>
			<td></td>
		</tr>
	</table>
</div>

Forms

Basic example

Individual form controls automatically receive some global styling. All textual <input>, <textarea>, and <select> elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.

<form role="form">
	<div class="form-group">
		<label for="exampleInputEmail1">Email address</label>
		<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
	</div>
	<div class="form-group">
		<label for="exampleInputPassword1">Password</label>
		<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
	</div>
	<div class="form-group">
		<label for="exampleInputFile">File input</label>
		<input type="file" id="exampleInputFile">
		<p class="help-block">Example block-level help text here.</p>
	</div>
	<div class="checkbox">
		<label>
		<input type="checkbox"> Check me out
		</label>
	</div>
	<button type="submit" class="btn btn-default">Submit</button>
</form>

Search form

Example form with search icon.

<form role="form" autocomplete="off">
	<div class="form-group has-feedback">
		<input name="search-form-example" class="form-control" type="text" placeholder="Search...">
		<i class="flaticon flaticon-search icon-sm form-control-feedback" aria-hidden="true"></i>
	</div>
</form>

Inline form

Add .form-inline to your <form> for left-aligned and inline-block controls. This only applies to forms within viewports that are at least 768px wide.

<form class="form-inline" role="form">
	<div class="form-group">
		<label class="sr-only" for="exampleInputEmail2">Email address</label>
		<input type="email" class="form-control" id="exampleInputEmail2" placeholder="Enter email">
	</div>
	<div class="form-group">
		<div class="input-group">
			<div class="input-group-addon">@</div>
			<input class="form-control" type="email" placeholder="Enter email">
		</div>
	</div>
	<div class="form-group">
		<label class="sr-only" for="exampleInputPassword2">Password</label>
		<input type="password" class="form-control" id="exampleInputPassword2" placeholder="Password">
	</div>
	<div class="checkbox">
		<label>
		<input type="checkbox"> Remember me
		</label>
	</div>
	<button type="submit" class="btn btn-default">Sign in</button>
</form>

Horizontal form

Use Style Guide's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal to the form. Doing so changes .form-groups to behave as grid rows, so no need for .row.

<form class="form-horizontal" role="form">
	<div class="form-group">
		<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
		<div class="col-sm-10">
			<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
		</div>
	</div>
	<div class="form-group">
		<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
		<div class="col-sm-10">
			<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
		</div>
	</div>
	<div class="form-group">
		<div class="col-sm-offset-2 col-sm-10">
			<div class="checkbox">
				<label>
				<input type="checkbox"> Remember me
				</label>
			</div>
		</div>
	</div>
	<div class="form-group">
		<div class="col-sm-offset-2 col-sm-10">
			<button type="submit" class="btn btn-default">Sign in</button>
		</div>
	</div>
</form>

Supported controls

Examples of standard form controls supported in an example form layout.

Inputs

Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.

<input type="text" class="form-control" placeholder="Text input">

Textarea

Form control which supports multiple lines of text. Change rows attribute as necessary.

<textarea class="form-control" rows="3"></textarea>

Checkboxes and radios

Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.

A checkbox or radio with the disabled attribute will be styled appropriately. To have the <label> for the checkbox or radio also display a "not-allowed" cursor when the user hovers over the label, add the .disabled class to your .radio, .radio-inline, .checkbox, .checkbox-inline, or <fieldset>.

Default (stacked)

<div class="checkbox">
	<label>
	<input type="checkbox" value="">
	Option one is this and that—be sure to include why it's great
	</label>
</div>
<div class="checkbox disabled">
	<label>
	<input type="checkbox" value="" disabled>
	Option two is disabled
	</label>
</div>
<div class="radio">
	<label>
	<input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
	Option one is this and that—be sure to include why it's great
	</label>
</div>
<div class="radio">
	<label>
	<input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
	Option two can be something else and selecting it will deselect option one
	</label>
</div>
<div class="radio disabled">
	<label>
	<input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
	Option three is disabled
	</label>
</div>

Inline checkboxes and radios

Use the .checkbox-inline or .radio-inline classes on a series of checkboxes or radios for controls that appear on the same line.

<label class="checkbox-inline">
	<input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="checkbox-inline">
	<input type="checkbox" id="inlineCheckbox2" value="option2"> 2
</label>
<label class="checkbox-inline">
	<input type="checkbox" id="inlineCheckbox3" value="option3"> 3
</label>
<label class="radio-inline">
	<input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>
<label class="radio-inline">
	<input type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2"> 2
</label>
<label class="radio-inline">
	<input type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3"> 3
</label>

Selects

Use the default option, or add multiple to show multiple options at once.

<select class="form-control">
	<option>1</option>
	<option>2</option>
	<option>3</option>
	<option>4</option>
	<option>5</option>
</select>
<select multiple class="form-control">
	<option>1</option>
	<option>2</option>
	<option>3</option>
	<option>4</option>
	<option>5</option>
</select>

Static control

When you need to place plain text next to a form label within a horizontal form, use the .form-control-static class on a <p>.

<form class="form-horizontal" role="form">
	<div class="form-group">
		<label class="col-sm-2 control-label">Email</label>
		<div class="col-sm-10">
			<p class="form-control-static">email@example.com</p>
		</div>
	</div>
	<div class="form-group">
		<label for="inputPassword" class="col-sm-2 control-label">Password</label>
		<div class="col-sm-10">
			<input type="password" class="form-control" id="inputPassword" placeholder="Password">
		</div>
	</div>
</form>

Input focus

We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.

Disabled inputs

Add the disabled boolean attribute on an input to prevent user input and trigger a slightly different look.

<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>

Disabled fieldsets

Add the disabled attribute to a <fieldset> to disable all the controls within the <fieldset> at once.

<form role="form">
	<fieldset disabled>
		<div class="form-group">
			<label for="disabledTextInput">Disabled input</label>
			<input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
		</div>
		<div class="form-group">
			<label for="disabledSelect">Disabled select menu</label>
			<select id="disabledSelect" class="form-control">
				<option>Disabled select</option>
			</select>
		</div>
		<div class="checkbox">
			<label>
			<input type="checkbox"> Can't check this
			</label>
		</div>
		<button type="submit" class="btn btn-primary">Submit</button>
	</fieldset>
</form>

Readonly inputs

Add the readonly boolean attribute on an input to prevent user input and style the input as disabled.

<input class="form-control" type="text" placeholder="Readonly input here…" readonly>

Validation states

Style Guide includes validation styles for error, warning, and success states on form controls. To use, add .has-warning, .has-error, or .has-success to the parent element. Any .control-label, .form-control, and .help-block within that element will receive the validation styles.

<div class="form-group has-success">
	<label class="control-label" for="inputSuccess1">Input with success</label>
	<input type="text" class="form-control" id="inputSuccess1">
	<p class="help-block">Example block-level help text here.</p>
</div>
<div class="form-group has-warning">
	<label class="control-label" for="inputWarning1">Input with warning</label>
	<input type="text" class="form-control" id="inputWarning1">
	<p class="help-block">Example block-level help text here.</p>
</div>
<div class="form-group has-error">
	<label class="control-label" for="inputError1">Input with error</label>
	<input type="text" class="form-control" id="inputError1">
	<p class="help-block">Example block-level help text here.</p>
</div>
<div class="form-group has-info">
	<label class="control-label" for="inputInfo1">Input with info</label>
	<input type="text" class="form-control" id="inputInfo1">
	<p class="help-block">Example block-level help text here.</p>
</div>

With optional icons

You can also add optional feedback icons with the addition of .has-feedback and the right icon.

<div class="form-group has-success has-feedback">
	<label class="control-label" for="inputSuccess2">Input with success</label>
	<input type="text" class="form-control" id="inputSuccess2">
	<i class="flaticon flaticon-check-circle icon-sm form-control-feedback" aria-hidden="true"></i>
</div>
<div class="form-group has-warning has-feedback">
	<label class="control-label" for="inputWarning2">Input with warning</label>
	<input type="text" class="form-control" id="inputWarning2">
	<i class="flaticon flaticon-alert icon-sm form-control-feedback" aria-hidden="true"></i>
</div>
<div class="form-group has-error has-feedback">
	<label class="control-label" for="inputError2">Input with error</label>
	<input type="text" class="form-control" id="inputError2">
	<i class="flaticon flaticon-info icon-sm form-control-feedback" aria-hidden="true"></i>
</div>
<div class="form-group has-info has-feedback">
	<label class="control-label" for="inputInfo2">Input with info</label>
	<input type="text" class="form-control" id="inputInfo2">
	<i class="flaticon flaticon-info icon-sm form-control-feedback" aria-hidden="true"></i>
</div>

Optional icons in horizontal and inline forms

<form class="form-horizontal" role="form">
	<div class="form-group has-success has-feedback">
		<label class="control-label col-sm-3" for="inputSuccess3">Input with success</label>
		<div class="col-sm-9">
			<input type="text" class="form-control" id="inputSuccess3">
			<i class="flaticon flaticon-check-circle icon-sm form-control-feedback" aria-hidden="true"></i>
		</div>
	</div>
</form>

<form class="form-inline" role="form">
	<div class="form-group has-success has-feedback">
		<label class="control-label" for="inputSuccess4">Input with success</label>
		<input type="text" class="form-control" id="inputSuccess4">
		<i class="flaticon flaticon-check-circle icon-sm form-control-feedback" aria-hidden="true"></i>
	</div>
</form>

Optional icons with hidden .sr-only labels

For form controls with no visible label, add the .sr-only class on the label. Style Guide will automatically adjust the position of the icon once it's been added.

<div class="form-group has-success has-feedback">
	<label class="control-label sr-only" for="inputSuccess5">Hidden label</label>
	<input type="text" class="form-control" id="inputSuccess5">
	<i class="flaticon flaticon-check-circle icon-sm form-control-feedback" aria-hidden="true"></i>
</div>

Control sizing

Set heights using classes like .input-lg, and set widths using grid column classes like .col-lg-*.

Height sizing

Create taller or shorter form controls that match button sizes.

<input class="form-control input-lg" type="text" placeholder=".input-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control input-sm" type="text" placeholder=".input-sm">
<select class="form-control input-lg">...</select>
<select class="form-control">...</select>
<select class="form-control input-sm">...</select>

Horizontal form group sizes

Quickly size labels and form controls within .form-horizontal by adding .form-group-lg or .form-group-sm.

<form class="form-horizontal" role="form">
	<div class="form-group form-group-lg clearfix">
		<label class="col-sm-2 control-label" for="formGroupInputLarge">Large label</label>
		<div class="col-sm-10">
			<input class="form-control" type="text" id="formGroupInputLarge" placeholder="Large input">
		</div>
	</div>
	<div class="form-group form-group-sm">
		<label class="col-sm-2 control-label" for="formGroupInputSmall">Small label</label>
		<div class="col-sm-10">
			<input class="form-control" type="text" id="formGroupInputSmall" placeholder="Small input">
		</div>
	</div>
</form>

Column sizing

Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.

<div class="row">
	<div class="col-xs-2">
		<input type="text" class="form-control" placeholder=".col-xs-2">
	</div>
	<div class="col-xs-3">
		<input type="text" class="form-control" placeholder=".col-xs-3">
	</div>
	<div class="col-xs-4">
		<input type="text" class="form-control" placeholder=".col-xs-4">
	</div>
</div>

Help text

Block level help text for form controls.

<span class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>

Skeleton Loader

This class adds the skeleton-loader style to an element, this is used when it is necessary to show for the user that certain content is in its loading state, providing feedback to the user of this state.

HTML code from the example above:

    <div class="row col-md-12">
      <h5>
        Requests
      </h5>
    </div>
    <div class="row">
