/Bootstrap 4


Bootstrap includes simple and easily customized typography for headings, body text, lists, and more. For even more control, check out the textual utility classes.


Global settings

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

  • Use a native font stack that selects the best font-family for each OS and device.
  • For a more inclusive and accessible type scale, we assume the browser default root font-size (typically 16px) so visitors can customize their browser defaults as needed.
  • Use the $font-family-base, $font-size-base, and $line-height-base attributes as our typographic base applied to the <body>.
  • Set the global link color via $link-color and apply link underlines only on :hover.
  • Use $body-bg to set a background-color on the <body> (#fff by default).

These styles can be found within _reboot.scss, and the global variables are defined in _variables.scss.


All HTML headings, <h1> through <h6>, are available.

<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>

.h1 through .h6 classes are also available, for when you want to match the font styling of a heading but cannot use the associated HTML element.

<p class="h1">h1. Bootstrap heading</p>
<p class="h2">h2. Bootstrap heading</p>
<p class="h3">h3. Bootstrap heading</p>
<p class="h4">h4. Bootstrap heading</p>
<p class="h5">h5. Bootstrap heading</p>
<p class="h6">h6. Bootstrap heading</p>

Customizing headings

Use the included utility classes to recreate the small secondary heading text from Bootstrap 3.

  Fancy display heading
  <small class="text-muted">With faded secondary text</small>

Display headings

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.

<h1 class="display-1">Display 1</h1>
<h1 class="display-2">Display 2</h1>
<h1 class="display-3">Display 3</h1>
<h1 class="display-4">Display 4</h1>


Make a paragraph stand out by adding .lead.

<p class="lead">
  Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.

Inline text elements

Styling for common inline HTML5 elements.

<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>

.mark and .small classes are also available to apply the same styles as <mark> and <small> while avoiding any unwanted semantic implications that the tags would bring.

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.

Text utilities

Change text alignment, transform, style, weight, and color with our text utilities.


Stylized implementation of HTML’s <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations have a default underline from Normalize.css and gain a help cursor to provide additional context on hover and to users of assistive technologies.

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

<p><abbr title="attribute">attr</abbr></p>
<p><abbr title="HyperText Markup Language" class="initialism">HTML</abbr></p>


For quoting blocks of content from another source within your document. Wrap <blockquote class="blockquote"> around any HTML as the quote.

<blockquote class="blockquote">
  <p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>

Naming a source

Add a <footer class="blockquote-footer"> for identifying the source. Wrap the name of the source work in <cite>.

<blockquote class="blockquote">
  <p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>

Reverse layout

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

<blockquote class="blockquote blockquote-reverse">
  <p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>



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.

<ul class="list-unstyled">
  <li>Lorem ipsum dolor sit amet</li>
  <li>Consectetur adipiscing elit</li>
  <li>Integer molestie lorem at massa</li>
  <li>Facilisis in pretium nisl aliquet</li>
  <li>Nulla volutpat aliquam velit
      <li>Phasellus iaculis neque</li>
      <li>Purus sodales ultricies</li>
      <li>Vestibulum laoreet porttitor sem</li>
      <li>Ac tristique libero volutpat at</li>
  <li>Faucibus porta lacus fringilla vel</li>
  <li>Aenean sit amet erat nunc</li>
  <li>Eget porttitor lorem</li>


Remove a list’s bullets and apply some light margin with a combination of two classes, .list-inline and .list-inline-item.

<ul class="list-inline">
  <li class="list-inline-item">Lorem ipsum</li>
  <li class="list-inline-item">Phasellus iaculis</li>
  <li class="list-inline-item">Nulla volutpat</li>

Description list alignment

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.

<dl class="row">
  <dt class="col-sm-3">Description lists</dt>
  <dd class="col-sm-9">A description list is perfect for defining terms.</dd>

  <dt class="col-sm-3">Euismod</dt>
  <dd class="col-sm-9">Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.</dd>
  <dd class="col-sm-9 offset-sm-3">Donec id elit non mi porta gravida at eget metus.</dd>

  <dt class="col-sm-3">Malesuada porta</dt>
  <dd class="col-sm-9">Etiam porta sem malesuada magna mollis euismod.</dd>

  <dt class="col-sm-3 text-truncate">Truncated term is truncated</dt>
  <dd class="col-sm-9">Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</dd>

  <dt class="col-sm-3">Nesting</dt>
  <dd class="col-sm-9">
    <dl class="row">
      <dt class="col-sm-4">Nested definition list</dt>
      <dd class="col-sm-8">Aenean posuere, tortor sed cursus feugiat, nunc augue blandit nunc.</dd>

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-sizes and media queries you wish.

html {
  font-size: 14px;

@include media-breakpoint-up(sm) {
  html {
    font-size: 16px;

@include media-breakpoint-up(md) {
  html {
    font-size: 20px;

@include media-breakpoint-up(lg) {
  html {
    font-size: 28px;
