• stylesheet


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.

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

Body Copy

Bootstrap's global default font-size is 14px, with a line-height of 1.428. 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).

Lead body copy

Make a paragraph stand out by adding .lead.

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.

Inline text elements

Marked text

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

Deleted text

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

Strikethrough text

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

Inserted text

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

Underlined text

To underline text use the <u> tag.

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>.


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


For emphasizing a snippet of text with italics.

Alternate elements

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.

Alignment classes

Easily realign text to components with text alignment classes.

Transformation classes

Transform text in components with text capitalization classes.


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 and to users of assistive technologies.

Basic abbreviation


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


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


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 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>.

Alternate displays

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



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


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


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.


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


A list of terms with their associated descriptions.

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.


Horizontal description lists will truncate terms that are too long to fit in the left column with <text-overflow>. In narrower viewports, they will change to the default stacked layout.
