Bootstrap includes simple and easily customized typography for headings, body text, lists, and more. For even more control, check out the [textual utility classes]({{ site.baseurl }}/components/utilities/).
## Contents
* Will be replaced with the ToC, excluding the "Contents" header
{:toc}
## Global settings
Bootstrap sets basic global display, typography, and link styles. Specifically, we:
- Use `$body-bg` to set a `background-color` on the `<body>` (`#fff` by default)
- Use the `$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 `_reboot.scss`, and the global variables are defined in `_variables.scss`.
## Headings
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.
<divclass="bd-example bd-example-type">
<tableclass="table">
<tbody>
<tr>
<td><h1>h1. Bootstrap heading</h1></td>
<tdclass="type-info">Semibold 36px</td>
</tr>
<tr>
<td><h2>h2. Bootstrap heading</h2></td>
<tdclass="type-info">Semibold 30px</td>
</tr>
<tr>
<td><h3>h3. Bootstrap heading</h3></td>
<tdclass="type-info">Semibold 24px</td>
</tr>
<tr>
<td><h4>h4. Bootstrap heading</h4></td>
<tdclass="type-info">Semibold 18px</td>
</tr>
<tr>
<td><h5>h5. Bootstrap heading</h5></td>
<tdclass="type-info">Semibold 14px</td>
</tr>
<tr>
<td><h6>h6. Bootstrap heading</h6></td>
<tdclass="type-info">Semibold 12px</td>
</tr>
</tbody>
</table>
</div>
{% highlight html %}
<h1>h1. Bootstrap heading</h1>
<h2>h2. Bootstrap heading</h2>
<h3>h3. Bootstrap heading</h3>
<h4>h4. Bootstrap heading</h4>
<h5>h5. Bootstrap heading</h5>
<h6>h6. Bootstrap heading</h6>
{% endhighlight %}
### Customizing headings
Use the included utility classes to recreate the small secondary heading text from Bootstrap 3.
Traditional heading elements are designed to work best in the meat of your page content. When you need a heading to stand out, consider using a **display heading**—a larger, slightly more opinionated heading style.
<divclass="bd-example bd-example-type">
<tableclass="table">
<tbody>
<tr>
<td><h1class="display-1">Display 1</h1></td>
</tr>
<tr>
<td><h1class="display-2">Display 2</h1></td>
</tr>
<tr>
<td><h1class="display-3">Display 3</h1></td>
</tr>
<tr>
<td><h1class="display-4">Display 4</h1></td>
</tr>
</tbody>
</table>
</div>
{% highlight html %}
<h1class="display-1">Display 1</h1>
<h1class="display-2">Display 2</h1>
<h1class="display-3">Display 3</h1>
<h1class="display-4">Display 4</h1>
{% endhighlight %}
## Lead
Make a paragraph stand out by adding `.lead`.
{% example html %}
<pclass="lead">
Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.
</p>
{% endexample %}
## Inline text elements
Styling for common inline HTML5 elements.
{% example html %}
<p>You can use the mark tag to <mark>highlight</mark> text.</p>
<p><del>This line of text is meant to be treated as deleted text.</del></p>
<p><s>This line of text is meant to be treated as no longer accurate.</s></p>
<p><ins>This line of text is meant to be treated as an addition to the document.</ins></p>
<p><u>This line of text will render as underlined</u></p>
<p><small>This line of text is meant to be treated as fine print.</small></p>
<p><strong>This line rendered as bold text.</strong></p>
<p><em>This line rendered as italicized text.</em></p>
{% endexample %}
While not shown above, 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 and to users of assistive technologies.
Add `.initialism` to an abbreviation for a slightly smaller font-size.
For quoting blocks of content from another source within your document. Wrap `<blockquote class="blockquote">` around any <abbrtitle="HyperText Markup Language">HTML</abbr> as the quote.
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.
Align terms and descriptions horizontally by using our grid system's predefined classes (or semantic mixins). For longer terms, you can optionally add a `.text-truncate` class to truncate the text with an ellipsis.
{% example html %}
<dlclass="dl-horizontal">
<dtclass="col-sm-3">Description lists</dt>
<ddclass="col-sm-9">A description list is perfect for defining terms.</dd>
<dtclass="col-sm-3">Euismod</dt>
<ddclass="col-sm-9">Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.</dd>
<ddclass="col-sm-9 col-sm-offset-3">Donec id elit non mi porta gravida at eget metus.</dd>
<dtclass="col-sm-3">Malesuada porta</dt>
<ddclass="col-sm-9">Etiam porta sem malesuada magna mollis euismod.</dd>
<dtclass="col-sm-3 text-truncate">Truncated term is truncated</dt>
<ddclass="col-sm-9">Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</dd>
</dl>
{% endexample %}
## Responsive typography
*Responsive typography* refers to scaling text and components by simply adjusting the root element's `font-size` within a series of media queries. Bootstrap doesn't do this for you, but it's fairly easy to add if you need it.
Here's an example of it in practice. Choose whatever `font-size`s and media queries you wish.
