Reboot, a collection of element-specific CSS changes in a single file, kickstart Bootstrap to provide an elegant, consistent, and simple baseline to build upon.

On this page


Reboot builds upon Normalize, providing many HTML elements with somewhat opinionated styles using only element selectors.

Additional styling is done only with classes. For example, we reboot some <table> styles for a simpler baseline and later provide .table, .table-bordered, and more.

Here are our guidelines and reasons for choosing what to override in Reboot:kumoku

  • 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.
  • textDecoration = "underline" will apply the same styles as <u>.
  • textDecoration = "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.

You can use the mark tag to highlight text.

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

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

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.


Text utilities

Change text alignment, transform, style, weight, line-height, decoration and color with our text utilities and color utilities .


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 attribute to an abbreviation for a slightly smaller font-size.






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


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

  • 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 attribute to truncate the text with an ellipsis.

Description lists
A description list is perfect for defining terms.

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.
Nested definition list
I heard you like definition lists. Let me put a definition list inside your definition list.
