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).
Example

Lead body copy
Make a paragraph stand out by adding .lead.
Example
Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.Bootstrap Lead body copy.
<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.
Example
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
