Global settings

-
-

Get the lowdown on the key pieces of Bootstrap's infrastructure, including our approach to better, faster, stronger web development.

- -

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.

- -{% highlight html linenos %} - - - ... - -{% endhighlight %} - -

Mobile first

-

With Bootstrap 2, we added optional mobile friendly styles for key aspects of the framework. With Bootstrap 3, we've rewritten the project to be mobile friendly from the start. Instead of adding on optional mobile styles, they're baked right into the core. In fact, Bootstrap is mobile first. Mobile first styles can be found throughout the entire library instead of in separate files.

-

To ensure proper rendering and touch zooming, add the viewport meta tag to your <head>.

- -{% highlight html linenos %} - -{% endhighlight %} - -

Typography and links

-

Bootstrap sets basic global display, typography, and link styles. Specifically, we:

-
    -
  • Remove margin on the body
    • -
  • Set background-color: white; on the body
    • -
  • Use the @font-family-base, @font-size-base, and @line-height-base attributes as our typographic base
    • -
  • Set the global link color via @link-color and apply link underlines only on :hover
    • -
-

These styles can be found within scaffolding.less.

- -

Normalize reset

-

For improved cross-browser rendering, we use Normalize, a project by Nicolas Gallagher and Jonathan Neal.

- -
- - - - -
-
-

Grid system

-
-

Bootstrap includes a responsive, percent-based grid system that appropriately scales up to 12 columns as the device or viewport size increases—in other words, it's mobile first. It includes predefined classes for this, as well as powerful mixins for generating semantic layouts.

- -

Grid example

-

On mobile devices, the grid starts out stacked. Above 768px, it becomes horizontal as media queries kick in to apply floats and widths. To create a basic grid layout, wrap a series of .col-span-* elements within a .row. 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), even at mobile resolutions.

Offsetting columns

-

Move columns to the right using .col-offset-* classes. Each class increases the left margin of a column by a whole column. For example, .col-offset-4 moves .col-span-4 over four columns.

-
-
-
4
-
4 offset 4

3 offset 3
-
-
-
6 offset 6
-
-
-{% highlight html linenos %} -
-
...
-
...
-
-{% endhighlight %} - - -

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 12.

-
-
- Level 1: 9 columns -
-
- Level 2: 6 columns -
-
- Level 2: 6 columns -
-
-
-
-{% highlight html linenos %} -
-
- Level 1: 9 columns -
-
- Level 2: 6 columns -
-
- Level 2: 6 columns -
-
-
-
-{% endhighlight %} - -

Column ordering

-

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

LESS mixins and variables

-

In addition to prebuilt grid classes for fast layouts, Bootstrap 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.

-{% highlight css linenos %} -@grid-columns: 12; -@grid-gutter-width: 30px; -@grid-float-breakpoint: 768px; -{% endhighlight %} - -

Mixins

-

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

-{% highlight css linenos %} -// Creates a wrapper for a series of columns -.make-row() { - // Negative margin the row out to align the content of columns - margin-left: (@grid-gutter-width / -2); - margin-right: (@grid-gutter-width / -2); - // Then clear the floated columns - .clear_float(); -} - -// Generate the columns -.make-column(@columns) { - @media (min-width: @grid-float-breakpoint) { - float: left; - // Calculate width based on number of columns available - width: percentage(@columns / @grid-columns); - } - // Prevent columns from collapsing when empty - min-height: 1px; - // Set inner padding as gutters instead of margin - padding-left: (@grid-gutter-width / 2); - padding-right: (@grid-gutter-width / 2); -} - -// Generate the column offsets -.make-column-offset(@columns) { - @media (min-width: @grid-float-breakpoint) { - margin-left: percentage((@columns / @grid-columns)); - } -} -{% endhighlight %} - -

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.

-{% highlight css linenos %} -.wrapper { - .make-row(); -} -.content-main { - .make-column(8); -} -.content-secondary { - .make-column(3); - .make-column-offset(1); -} -{% endhighlight %} -{% highlight html linenos %} -

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.

-
-{% highlight html linenos %} -

...

-{% endhighlight %} - - -

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.

-
-{% highlight html linenos %} -

...

-{% endhighlight %} - - -

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 text

-

For de-emphasizing inline or blocks of text, use the small tag.

-
-

This line of text is meant to be treated as fine print.

-
-{% highlight html linenos %} -This line of text is meant to be treated as fine print. -{% endhighlight %} - - -

Bold

-

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

-
-

The following snippet of text is rendered as bold text.

-
-{% highlight html linenos %} -rendered as bold text -{% endhighlight %} - -

Italics

-

For emphasizing a snippet of text with italics.

-
-

The following snippet of text is rendered as italicized text.

-
-{% highlight html linenos %} -rendered as italicized text -{% endhighlight %} - -

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.

- -

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.

-
-

An abbreviation of the word attribute is attr.

-
-{% highlight html linenos %} -attr -{% endhighlight %} - -

- 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>.

-
- For example, <section> should be wrapped as inline. -
-{% highlight html linenos %} -For example, <section> should be wrapped as inline. -{% endhighlight %} - -

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>
-
-{% highlight html linenos %} -
<p>Sample text here...</p>
-{% endhighlight %} - -

You may optionally add the .pre-scrollable class which will set a max-height of 350px and provide a y-axis scrollbar.

-
- - - - -
-
-

Tables

-
- -

Default styles

-

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.

Style inputs via default browser functionality with :invalid. Specify a type, add the required attribute if the field is not optional, and (if applicable) specify a pattern.

-

This is not available in versions of Internet Explorer 7-9 due to lack of support for CSS pseudo selectors.

-
- -
-{% highlight html linenos %} - -{% endhighlight %} - -

Disabled inputs

-

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

-
- -
-{% highlight html linenos %} - -{% endhighlight %} - -

Disabled fieldsets

-

Add the disabled attribute to a <fieldset> to disable all the controls within the <fieldset> at once. Link buttons (with the <a> element) will be aesthetically disabled, but you will need custom JavaScript to disable their behavior.

Validation states

-

Bootstrap includes validation styles for error, warning, info, and success messages. To use:

-
    -
  • Add .has-warning, .has-error, or .has-success to the parent element
    • -
  • Add .input-with-feedback to the field(s) in question
    • -
-

Validation styles are applied on a per-input basis. With horizontal forms, the <label class="control-label"> will always be styled.

-
- -
- -
-
-{% endhighlight %} - - - -

Extending form controls

-

Adding on top of existing browser controls, Bootstrap includes other useful form components.

- -

Input groups

-

Add text or buttons before, after, or on both sides of any text-based input. Use .input-group with a .add-on to prepend or append elements to an <input>.

-

Avoid using <select> elements here as they cannot be fully styled in WebKit browsers.

-
-{% highlight html linenos %} -
- @ - -
- -
- - .00 -
- -
- $ - - .00 -
-{% endhighlight %} - -

Optional sizes

-

Add the relative form sizing classes to the `.input-group-addon`.

-
-
- @ - -
-
-

-
-

-
-{% highlight html linenos %} -
- @ - -
- -
- @ - -
- -
- @ - -
-{% endhighlight %} - -

Buttons instead of text

-

Buttons in input groups are a bit different and require one extra level of nesting. Instead of .input-group-addon, you'll need to use .input-group-btn to wrap the buttons. This is required due to default browser styles that cannot be overridden.

-
-
- - - - -
-
-
- - - - -
-
-{% highlight html linenos %} -
- - - - -

- - - - -

-
-
-{% highlight html linenos %} -
-
- -

- -
- -
- -
-
-{% endhighlight %} - -

Control sizing

-

Use relative sizing classes like .input-large or match your inputs to the grid column sizes using .span* classes.

- -

Relative sizing

-

Create larger or smaller form controls that match button sizes.

-
-
- - - -
-
-{% highlight html linenos %} - - - -{% endhighlight %} - -

Column sizing

-

Use .span1 to .span12 for setting widths on inputs that match Bootstrap's grid system.

-
-
- - - - - - -
-
-{% highlight html linenos %} - - - - - - -{% endhighlight %} - -

If you need multiple inputs on the same line, wrap them in the standard grid markup (with .row and .span* classes). Each input should have it's own column and will expand to fill the available width automatically.

-

-
- -
-
- -
-
-
-{% highlight html linenos %} -
-
- -
-
- -
-
- -
-
-{% endhighlight %} - -

Uneditable inputs

-

Present data in a form that's not editable without using actual form markup.

-
- Some value here -
-{% highlight html linenos %} -Some value here -{% endhighlight %} - -

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.

-
-
- - -
-
-{% highlight html linenos %} -
- - -
-{% endhighlight %} - -

Help text

-

Inline and block level support for help text that appears around form controls.

-

Inline help

-
- Inline help text -
-{% highlight html linenos %} - -Inline help text -{% endhighlight %} - -

Block help

-
- - A longer block of help text that breaks onto a new line and may extend beyond one line. -
-{% highlight html linenos %} - -A longer block of help text that breaks onto a new line and may extend beyond one line. -{% endhighlight %} - -
- - - - -
-
-

Buttons

-
- -

Default buttons

-

Button styles can be applied to anything with the .btn class applied. However, typically you'll want to apply these to only <a> and <button> elements for the best rendering.

-
- - - - - - - -
-{% highlight html linenos %} - - - - - - - - - - - - - - - - - - - - -{% endhighlight %} - -

Cross browser compatibility

-

IE9 doesn't crop background gradients on rounded corners, so we remove it. Related, IE9 jankifies disabled button elements, rendering text gray with a nasty text-shadow that we cannot fix.

- - -

Button sizes

-

Fancy larger or smaller buttons? Add .btn-large, .btn-small, or .btn-mini for additional sizes.

-
-

-

- - -

-{% endhighlight %} - -

Create block level buttons—those that span the full width of a parent— by adding .btn-block.

-
-
- - -
-
-{% highlight html linenos %} - - -{% endhighlight %} - - -

Disabled state

-

Make buttons look unclickable by fading them back 50%.

- -

Button element

-

Add the disabled attribute to <button> buttons.

-

- - -

-{% highlight html linenos %} - - -{% endhighlight %} - -

Anchor element

-

Add the .disabled class to <a> buttons.

-

- Primary link - Link -

-{% highlight html linenos %} -Primary link -Link -{% endhighlight %} -

- We use .disabled as a utility class here, similar to the common .active class, so no prefix is required. Also, this class is only for aesthetic; you must use custom JavaScript to disable links here. -

- - -

One class, multiple tags

-

Use the .btn class on an <a>, <button>, or <input> element.

-
- Link - - - -
-{% highlight html linenos %} -Link - - - -{% endhighlight %} -

As a best practice, we highly recommend matching using the <button< element whenever possible to ensure matching cross-browser rendering.

- -
- - - - -
-
-

Images

-
- -

Add classes to an <img> element to easily style images in any project. Rounded corners are not available in IE8.

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:

-{% highlight html linenos %} - -{% endhighlight %} -

Want to change the icon color? Just change the color of the parent element.

-

When using beside strings of text, as in buttons or nav links, be sure to leave a space after the icon for proper spacing.

- - -

Icon examples

-

Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.

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.

- -

Test case

-

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

-
