Global settings

Bootstrap sets basic global display, typography, and link styles. When more control is needed, check out the textual utility classes .

  • 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 use the browser ’s 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 .
  • 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.

Beware that those tags should be used for semantic purpose:

  • <mark > represents text which is marked or highlighted for reference or notation purposes.
  • <small > represents side-comments and small print, like copyright and legal text.
  • <s > represents element that are no longer relevant or no longer accurate.
  • <u > represents a span of inline text which should be rendered in a way that indicates that it has a non-textual annotation.

If you want to style your text, you should use the following classes instead:

  • .mark will apply the same styles as <mark > .
  • .small will apply the same styles as <small > .
  • .text-decoration-underline will apply the same styles as <u > .
  • .text-decoration-line-through will apply the same styles as <s > .

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, line-height, decoration and color with our text utilities and color utilities .

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.

Naming a source

The HTML spec requires that blockquote attribution be placed outside the <blockquote > . When providing attribution, wrap your <blockquote > in a <figure > and use a <figcaption > or a block level element (e.g., <p > ) with the .blockquote-footer class. Be sure to wrap the name of the source work in <cite > as well.

A well-known quote, contained in a blockquote element.

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.

  • This is a list.
  • It appears completely unstyled.
  • Structurally, it's still a list.
  • However, this style only applies to immediate child elements.
  • Nested lists:
    • are unaffected by this style
    • will still show a bullet
    • and have appropriate left margin
  • This may still come in handy in some situations.

Inline

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

  • This is a list item.
  • And another one.
  • But they're displayed inline.

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.

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

Definition for the term.

And some more placeholder definition text.

Another term
This definition is short, so no extra paragraphs or anything.
Truncated term is truncated
This can be useful when space is tight. Adds an ellipsis at the end.
Nesting
Nested definition list
I heard you like definition lists. Let me put a definition list inside your definition list.

Responsive font sizes

In Bootstrap 5, we ’ve enabled responsive font sizes by default, allowing text to scale more naturally across device and viewport sizes. Have a look at the RFS page to find out how this works.

CSS

Sass variables
