docs Typography Documentation and examples for Bootstrap typography, including global settings, headings, body text, lists, and more. content true

Global settings

Bootstrap sets basic global display, typography, and link styles. When more control is needed, check out the [textual utility classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/).

  • Use a [native font stack]({{ site.baseurl }}/docs/{{ site.docs_version }}/content/reboot/#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. Make sure to set $font-size-base in rem.

Headings

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

Heading Example
{{ "`

`" | markdownify }}
h1. Bootstrap heading
{{ "`

`" | markdownify }}
h2. Bootstrap heading
{{ "`

`" | markdownify }}
h3. Bootstrap heading
{{ "`

`" | markdownify }}
h4. Bootstrap heading
{{ "`
`" | markdownify }}
h5. Bootstrap heading
{{ "`

h6. Bootstrap heading

{% highlight html %}

h1. Bootstrap heading

h2. Bootstrap heading

h3. Bootstrap heading

h4. Bootstrap heading

h5. Bootstrap heading
h6. Bootstrap heading
{% endhighlight %}

.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.

{% capture example %}

h1. Bootstrap heading

h2. Bootstrap heading

h3. Bootstrap heading

h4. Bootstrap heading

h5. Bootstrap heading

h6. Bootstrap heading

{% endcapture %} {% include example.html content=example %}

Customizing headings

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

{% capture example %}

Fancy display heading With faded secondary text

{% endcapture %} {% include example.html content=example %}

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. Keep in mind these headings are not responsive by default, but it's possible to enable responsive font sizes.

Display 1
Display 2
Display 3
Display 4

{% highlight html %}

Display 1

Display 2

Display 3

Display 4

{% endhighlight %}

Lead

Make a paragraph stand out by adding .lead.

{% capture example %}

Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.

{% endcapture %} {% include example.html content=example %}

Inline text elements

Styling for common inline HTML5 elements.

{% capture example %}

You can use the mark tag to highlight text.

This line of text is meant to be treated as deleted text.

This line of text is meant to be treated as no longer accurate.

This line of text is meant to be treated as an addition to the document.

This line of text will render as underlined

This line of text is meant to be treated as fine print.

This line rendered as bold text.

This line rendered as italicized text.

{% endcapture %} {% include example.html content=example %}

.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]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/) and [color utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/).

Abbreviations

Stylized implementation of HTML's <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations have a default underline 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.

{% capture example %}

attr

HTML

{% endcapture %} {% include example.html content=example %}

Blockquotes

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

{% capture example %}

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

{% endcapture %} {% include example.html content=example %}

Naming a source

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

{% capture example %}

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
{% endcapture %} {% include example.html content=example %}

Alignment

Use text utilities as needed to change the alignment of your blockquote.

{% capture example %}

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
{% endcapture %} {% include example.html content=example %}

{% capture example %}

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
{% endcapture %} {% include example.html content=example %}

Lists

Unstyled

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.

{% capture example %}

  • Lorem ipsum dolor sit amet
  • Consectetur adipiscing elit
  • Integer molestie lorem at massa
  • Facilisis in pretium nisl aliquet
  • Nulla volutpat aliquam velit
    • Phasellus iaculis neque
    • Purus sodales ultricies
    • Vestibulum laoreet porttitor sem
    • Ac tristique libero volutpat at
  • Faucibus porta lacus fringilla vel
  • Aenean sit amet erat nunc
  • Eget porttitor lorem
{% endcapture %} {% include example.html content=example %}

Inline

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

{% capture example %}

  • Lorem ipsum
  • Phasellus iaculis
  • Nulla volutpat
{% endcapture %} {% include example.html content=example %}

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.

{% capture example %}

Description lists
A description list is perfect for defining terms.
Euismod

Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.

Donec id elit non mi porta gravida at eget metus.

Malesuada porta
Etiam porta sem malesuada magna mollis euismod.
Truncated term is truncated
Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.
Nesting
Nested definition list
Aenean posuere, tortor sed cursus feugiat, nunc augue blandit nunc.
{% endcapture %} {% include example.html content=example %}

Responsive font sizes

Bootstrap v4.3 ships with the option to enable responsive font sizes, allowing text to scale more naturally across device and viewport sizes. RFS can be enabled by changing the $enable-responsive-font-sizes Sass variable to true and recompiling Bootstrap.

To support RFS, we use a Sass mixin to replace our normal font-size properties. Responsive font sizes will be compiled into calc() functions with a mix of rem and viewport units to enable the responsive scaling behavior. More about RFS and its configuration can be found on its GitHub repository.
