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).
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.

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 highlight text.
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.
This line of text is meant to be treated as deleted text.
<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.
This line of text is meant to be treated as no longer accurate.
<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.
This line of text is meant to be treated as an addition to the document.
<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.
This line of text will render as underlined
<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>.
This line of text is meant to be treated as fine print.
<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.
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>

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.
Left aligned text.
Center aligned text.
Right aligned text.
Justified text.

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 and to users of assistive technologies.

Basic abbreviation

An abbreviation of the word attribute is attr.
<abbr title="attribute">attr</abbr>

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>

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