CSS
+Fundamental HTML elements styled and enhanced with extensible classes.
+Global settings
+Requires HTML5 doctype
+Bootstrap makes use of certain HTML elements and CSS properties that require the use of the HTML5 doctype. Include it at the beginning of all your projects.
++<!DOCTYPE html> +<html lang="en"> + ... +</html> ++ +
Typography and links
+Bootstrap sets basic global display, typography, and link styles. Specifically, we:
+-
+
- Remove
marginon the body
+ - Set
background-color: white;on thebody
+ - Use the
@font-family-base,@font-size-base, and@line-height-baseattributes as our typographic base
+ - Set the global link color via
@link-colorand apply link underlines only on:hover
+
These styles can be found within scaffolding.less.
+ +Reset via Normalize
+With Bootstrap 2, the old reset block has been dropped in favor of Normalize.css, a project by Nicolas Gallagher and Jonathan Neal that also powers the HTML5 Boilerplate. While we use much of Normalize within our reset.less, we have removed some elements specifically for Bootstrap.
+ +Default grid system
+Live grid example
+The default Bootstrap grid system utilizes 12 columns, making for a 940px wide container without responsive features enabled. With the responsive CSS file added, the grid adapts to be 724px and 1170px wide depending on your viewport. Below 767px viewports, the columns become fluid and stack vertically.
+Basic grid HTML
+For a simple two column layout, create a .row and add the appropriate number of .span* columns. As this is a 12-column grid, each .span* spans a number of those 12 columns, and should always add up to 12 for each row (or the number of columns in the parent).
+<div class="row"> + <div class="span4">...</div> + <div class="span8">...</div> +</div> ++
Given this example, we have .span4 and .span8, making for 12 total columns and a complete row.
Offsetting columns
+Move columns to the right using .offset* classes. Each class increases the left margin of a column by a whole column. For example, .offset4 moves .span4 over four columns.
+<div class="row"> + <div class="span4">...</div> + <div class="span4 offset4">...</div> +</div> ++ + +
Nesting columns
+To nest your content with the default grid, add a new .row and set of .span* columns within an existing .span* column. Nested rows should include a set of columns that add up to the number of columns of its parent.
+<div class="row"> + <div class="span9"> + Level 1 column + <div class="row"> + <div class="span6">Level 2</div> + <div class="span3">Level 2</div> + </div> + </div> +</div> ++
Typography
+Headings
+All HTML headings, <h1> through <h6> are available.
h1. Heading 1
+h2. Heading 2
+h3. Heading 3
+h4. Heading 4
+h5. Heading 5
+h6. Heading 6
+Body copy
+Bootstrap's global default font-size is 14px, with a line-height of 20px. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their line-height (10px by default).
Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Nullam id dolor id nibh ultricies vehicula.
+Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec ullamcorper nulla non metus auctor fringilla. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Donec ullamcorper nulla non metus auctor fringilla.
+Maecenas sed diam eget risus varius blandit sit amet non magna. Donec id elit non mi porta gravida at eget metus. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit.
+<p>...</p>+ +
Lead body copy
+Make a paragraph stand out by adding .lead.
Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.
+<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 Bootstrap adapts.
+ + +
Emphasis
+Make use of HTML's default emphasis tags with lightweight styles.
+ +<small>
+ For de-emphasizing inline or blocks of text, use the small tag.
+This line of text is meant to be treated as fine print.
++<p> + <small>This line of text is meant to be treated as fine print.</small> +</p> ++ +
Bold
+For emphasizing a snippet of text with a heavier font-weight.
+The following snippet of text is rendered as bold text.
+<strong>rendered as bold text</strong>+ +
Italics
+For emphasizing a snippet of text with italics.
+The following snippet of text is rendered as italicized text.
+<em>rendered as italicized text</em>+ +
Heads up! Feel free to use <b> and <i> in HTML5. <b> is meant to highlight words or phrases without conveying additional importance while <i> is mostly for voice, technical terms, etc.
Emphasis classes
+Convey meaning through color with a handful of emphasis utility classes.
+Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.
+Etiam porta sem malesuada magna mollis euismod.
+Donec ullamcorper nulla non metus auctor fringilla.
+Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis.
+Duis mollis, est non commodo luctus, nisi erat porttitor ligula.
++<p class="muted">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-error">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> ++ + +
+ + +
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.
<abbr>
+ For expanded text on long hover of an abbreviation, include the title attribute.
An abbreviation of the word attribute is attr.
+<abbr title="attribute">attr</abbr>+ +
<abbr class="initialism">
+ Add .initialism to an abbreviation for a slightly smaller font-size.
HTML is the best thing since sliced bread.
+<abbr title="HyperText Markup Language" class="initialism">HTML</abbr>+ + +
+ + +
Addresses
+Present contact information for the nearest ancestor or the entire body of work.
+ +<address>
+ Preserve formatting by ending all lines with <br>.
+ 795 Folsom Ave, Suite 600
+ San Francisco, CA 94107
+ P: (123) 456-7890 + + + Full Name
+ first.last@example.com + +
+<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>.
++Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
+
+<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 <small> tag for identifying the source. Wrap the name of the source work in <cite>.
++Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
+ Someone famous in Source Title +
+<blockquote> + <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p> + <small>Someone famous <cite title="Source Title">Source Title</cite></small> +</blockquote> ++ +
Alternate displays
+Use .pull-right for a floated, right-aligned blockquote.
+<blockquote class="pull-right"> + ... +</blockquote> ++ + +
+ + + +

+ Heads up!
+ Horizontal description lists will truncate terms that are too long to fit in the left column fix text-overflow. In narrower viewports, they will change to the default stacked layout.
+
Code
+Inline
+Wrap inline snippets of code with <code>.
<section> should be wrapped as inline.
++For example, <code><section></code> should be wrapped as inline. ++ +
Basic block
+Use <pre> for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.
<p>Sample text here...</p>+
+<pre> + <p>Sample text here...</p> +</pre> ++
Heads up! Be sure to keep code within <pre> tags as close to the left as possible; it will render all tabs.
You may optionally add the .pre-scrollable class which will set a max-height of 350px and provide a y-axis scrollbar.

Forms
+Default styles
+Individual form controls automatically receive some global styling. By default, inputs are set to width: 100%;.
+<form> + <fieldset> + <legend>Legend</legend> + <label>Label name</label> + <input type="text" placeholder="Type something…"> + <span class="help-block">Example block-level help text here.</span> + <div class="checkbox"> + <label> + <input type="checkbox"> Check me out + </label> + </div> + <button type="submit" class="btn">Submit</button> + </fieldset> +</form> ++ + +
+ + +
Optional layouts
+Included with Bootstrap are three optional form layouts for common use cases.
+ +Search form
+Add .form-search to the form and .search-query to the <input> for an extra-rounded text input.
+<form class="form-search"> + <input type="text" class="span3 search-query"> + <button type="submit" class="btn">Search</button> +</form> ++ +
Inline form
+Add .form-inline for left-aligned labels and inline-block controls for a compact layout.
+<form class="form-inline"> + <input type="text" class="span3" placeholder="Email"> + <input type="password" class="span3" placeholder="Password"> + <div class="checkbox"> + <label> + <input type="checkbox"> Remember me + </label> + </div> + <button type="submit" class="btn">Sign in</button> +</form> ++ +
Horizontal form
+Right align labels and float them to the left to make them appear on the same line as controls. Requires the most markup changes from a default form:
+-
+
- Add
.form-horizontalto the form
+ - Wrap labels and controls in
.control-group
+ - Add
.control-labelto the label
+ - Wrap any associated controls in
.controlsfor proper alignment
+
+<form class="form-horizontal"> + <div class="control-group"> + <label class="control-label" for="inputEmail">Email</label> + <div class="controls"> + <input type="text" id="inputEmail" placeholder="Email"> + </div> + </div> + <div class="control-group"> + <label class="control-label" for="inputPassword">Password</label> + <div class="controls"> + <input type="password" id="inputPassword" placeholder="Password"> + </div> + </div> + <div class="control-group"> + <div class="controls"> + <label class="checkbox"> + <input type="checkbox"> Remember me + </label> + <button type="submit" class="btn">Sign in</button> + </div> + </div> +</form> ++ + +
+ + +
Supported form 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.
+Requires the use of a specified type at all times.
+<input type="text" placeholder="Text input"> ++ +
Textarea
+Form control which supports multiple lines of text. Change rows attribute as necessary.
+<textarea 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.
+Default (stacked)
+ ++<label class="checkbox"> + <input type="checkbox" value=""> + Option one is this and that—be sure to include why it's great +</label> + +<label class="radio"> + <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> +<label class="radio"> + <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2"> + Option two can be something else and selecting it will deselect option one +</label> ++ +
Inline checkboxes
+Add the .inline class to a series of checkboxes or radios for controls 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> ++ +
Selects
+Use the default option or specify a multiple="multiple" to show multiple options at once.
+<select> + <option>1</option> + <option>2</option> + <option>3</option> + <option>4</option> + <option>5</option> +</select> + +<select multiple="multiple"> + <option>1</option> + <option>2</option> + <option>3</option> + <option>4</option> + <option>5</option> +</select> ++ + +
+ + +
Extending form controls
+Adding on top of existing browser controls, Bootstrap includes other useful form components.
+ +Prepended and appended inputs
+Add text or buttons before or after any text-based input. Do note that select elements are not supported here.
Default options
+Wrap an .add-on and an input with one of two classes to prepend or append text to an input.
+<div class="input-prepend"> + <span class="add-on">@</span> + <input id="prependedInput" type="text" placeholder="Username"> +</div> +<div class="input-append"> + <input id="appendedInput" type="text"> + <span class="add-on">.00</span> +</div> ++ +
Combined
+Use both classes and two instances of .add-on to prepend and append an input.
+<div class="input-prepend input-append"> + <span class="add-on">$</span> + <input id="appendedPrependedInput" type="text"> + <span class="add-on">.00</span> +</div> ++ +
Buttons instead of text
+Instead of a <span> with text, use a .btn to attach a button (or two) to an input.
+<div class="input-append"> + <input class="span3" id="appendedInputButton" type="text"> + <button class="btn" type="button">Go!</button> +</div> ++ +
+<div class="input-append"> + <input class="span3" id="appendedInputButton" type="text"> + <button class="btn" type="button">Search</button> + <button class="btn" type="button">Options</button> +</div> ++ +
Button dropdowns
+ + ++<div class="input-append"> + <input id="appendedInputButtons" type="text"> + <input class="span3" id="appendedDropdownButton" type="text"> + <div class="btn-group"> + <button class="btn dropdown-toggle" data-toggle="dropdown"> + Action + <span class="caret"></span> + </button> + <ul class="dropdown-menu"> + ... + </ul> + </div> +</div> ++ + +
+<div class="input-prepend"> + <div class="btn-group"> + <button class="btn dropdown-toggle" data-toggle="dropdown"> + Action + <span class="caret"></span> + </button> + <ul class="dropdown-menu"> + ... + </ul> + </div> + <input class="span2" id="prependedDropdownButton" type="text"> +</div> ++ + +
+<div class="input-prepend input-append"> + <div class="btn-group"> + <button class="btn dropdown-toggle" data-toggle="dropdown"> + Action + <span class="caret"></span> + </button> + <ul class="dropdown-menu"> + ... + </ul> + </div> + <input class="span2" id="appendedPrependedDropdownButton" type="text"> + <div class="btn-group"> + <button class="btn dropdown-toggle" data-toggle="dropdown"> + Action + <span class="caret"></span> + </button> + <ul class="dropdown-menu"> + ... + </ul> + </div> +</div> ++ +
Segmented dropdown groups
+ ++<form> + <div class="input-prepend"> + <div class="btn-group">...</div> + <input type="text" class="span3"> + </div> + <div class="input-append"> + <input type="text" class="span3"> + <div class="btn-group">...</div> + </div> +</form> ++ +
Search form
+ ++<form class="form-search"> + <div class="input-append"> + <input type="text" class="search-query span3"> + <button type="submit" class="btn">Search</button> + </div> + <div class="input-prepend"> + <button type="submit" class="btn">Search</button> + <input type="text" class="search-query span3"> + </div> +</form> ++ +
Control sizing
+Use relative sizing classes like .input-large or match your inputs to the grid column sizes using .span* classes.
Block level inputs
+Make any <input> or <textarea> element behave like a block level element.
+<input class="input-block-level" type="text" placeholder=".input-block-level"> ++ +
Relative sizing
+Create larger or smaller form controls that match button sizes.
+ ++<input class="input-large" type="text" placeholder=".input-large"> +<input class="input-small" type="text" placeholder=".input-small"> +<input class="input-mini" type="text" placeholder=".input-mini"> ++ +
Column sizing
+Use .span1 to .span12 for setting widths on inputs that match Bootstrap's grid system.
+<input class="span1" type="text" placeholder=".span1"> +<input class="span2" type="text" placeholder=".span2"> +<input class="span3" type="text" placeholder=".span3"> +<select class="span1"> + ... +</select> +<select class="span2"> + ... +</select> +<select class="span3"> + ... +</select> ++ +
For multiple grid inputs per line, use the .controls-row modifier class for proper spacing. It floats the inputs to collapse white-space, sets the proper margins, and the clears the float.
+<div class="controls"> + <input class="span5" type="text" placeholder=".span5"> +</div> +<div class="controls controls-row"> + <input class="span4" type="text" placeholder=".span4"> + <input class="span1" type="text" placeholder=".span1"> +</div> +... ++ +
Uneditable inputs
+Present data in a form that's not editable without using actual form markup.
+ ++<span class="input-xlarge uneditable-input">Some value here</span> ++ +
Form actions
+End a form with a group of actions (buttons). When placed within a .form-horizontal, the buttons will automatically indent to line up with the form controls.
+<div class="form-actions"> + <button type="submit" class="btn btn-primary">Save changes</button> + <button type="button" class="btn">Cancel</button> +</div> ++ +
Help text
+Inline and block level support for help text that appears around form controls.
+Inline help
+ ++<input type="text"><span class="help-inline">Inline help text</span> ++ +
Block help
+ ++<input type="text"><span class="help-block">A longer block of help text that breaks onto a new line and may extend beyond one line.</span> ++ + +
+ + +
Form control states
+Provide feedback to users or visitors with basic feedback states on form controls and labels.
+ +Input focus
+We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.
+<input class="input-xlarge" id="focusedInput" type="text" value="This is focused..."> ++ +
Invalid inputs
+Style inputs via default browser functionality with :invalid. Specify a type and add the required attribute.
+<input class="span3" type="email" required> ++ +
Disabled inputs
+Add the disabled attribute on an input to prevent user input and trigger a slightly different look.
+<input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here..." disabled> ++ +
Validation states
+Bootstrap includes validation styles for error, warning, info, and success messages. To use, add the appropriate class to the surrounding .control-group.
+<div class="control-group warning"> + <label class="control-label" for="inputWarning">Input with warning</label> + <div class="controls"> + <input type="text" id="inputWarning"> + <span class="help-inline">Something may have gone wrong</span> + </div> +</div> +<div class="control-group error"> + <label class="control-label" for="inputError">Input with error</label> + <div class="controls"> + <input type="text" id="inputError"> + <span class="help-inline">Please correct the error</span> + </div> +</div> +<div class="control-group success"> + <label class="control-label" for="inputSuccess">Input with success</label> + <div class="controls"> + <input type="text" id="inputSuccess"> + <span class="help-inline">Woohoo!</span> + </div> +</div> ++ +
Images
+Add classes to an <img> element to easily style images in any project.
+<img src="..." class="img-rounded"> +<img src="..." class="img-circle"> +<img src="..." class="img-polaroid"> ++
Heads up! .img-rounded and .img-circle do not work in IE8 due to lack of border-radius support.
Icons font by Glyphicons
+Included glyphs
+Bootstrap comes with all 160 of Glyphicons Halflings set, all available in font formats for easy coloring, sizing, and placement.
+ + + +Glyphicons attribution
+Glyphicons Halflings are normally not available for free, but an arrangement between Bootstrap and the Glyphicons creator have made this possible at no cost to you as developers. As a thank you, we ask you to include an optional link back to Glyphicons whenever practical.
+ + ++ + +
How to use
+Add the appropriate class to any inline element. All icon classes are prefixed with glyphicon- for easy styling. To use, place the following code just about anywhere:
+<i class="glyphicon-search"></i> ++
Want to change the icon color? Just change the color of the parent element.
+ Heads up! + When using beside strings of text, as in buttons or nav links, be sure to leave a space after the icon for proper spacing. +
+ + ++ + +

About responsive Bootstrap
+
+ Media queries allow for custom CSS based on a number of conditions—ratios, widths, display type, etc—but usually focuses around min-width and max-width.
-
+
- Modify the width of column in our grid +
- Stack elements instead of float wherever necessary +
- Resize headings and text to be more appropriate for devices +
Use media queries responsibly and only as a start to your mobile audiences. For larger projects, do consider dedicated code bases and not layers of media queries.
+ +Supported devices
+Bootstrap supports a handful of media queries to help make your projects more appropriate on different devices and screen resolutions. Here's what's included:
+| Label | +Layout width | +Column width | +Gutter width | +
|---|---|---|---|
| Large display | +1200px and up | +70px | +30px | +
| Default | +980px and up | +60px | +20px | +
| Portrait tablets | +768px and above | +42px | +20px | +
| Phones to tablets | +767px and below | +Fluid columns, no fixed widths | +|
| Phones | +480px and below | +Fluid columns, no fixed widths | +|
+/* Large desktop */
+@media (min-width: 1200px) { ... }
+
+/* Portrait tablet to landscape and desktop */
+@media (min-width: 768px) and (max-width: 979px) { ... }
+
+/* Landscape phone to portrait tablet */
+@media (max-width: 767px) { ... }
+
+/* Landscape phones and down */
+@media (max-width: 480px) { ... }
+
+
+
+ Responsive utility classes
+For faster mobile-friendly development, use these utility classes for showing and hiding content by device. Below is a table of the available classes and their effect on a given media query layout (labeled by device). They can be found in responsive.less.
| Class | +Phones 767px and below | +Tablets 979px to 768px | +Desktops Default | +
|---|---|---|---|
.visible-phone |
+ Visible | +Hidden | +Hidden | +
.visible-tablet |
+ Hidden | +Visible | +Hidden | +
.visible-desktop |
+ Hidden | +Hidden | +Visible | +
.hidden-phone |
+ Hidden | +Visible | +Visible | +
.hidden-tablet |
+ Visible | +Hidden | +Visible | +
.hidden-desktop |
+ Visible | +Visible | +Hidden | +
When to use
+Use on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation. Responsive utilities should not be used with tables, and as such are not supported.
+ +Responsive utilities test case
+Resize your browser or load on different devices to test the above classes.
+Visible on...
+Green checkmarks indicate that class is visible in your current viewport.

+
- Phone✔ Phone +
- Tablet✔ Tablet +
