{{ CSSRef() }}

Summary

The border-bottom-width CSS property sets the width of the bottom border of a box.

  • {{ Xref_cssinitial() }}: medium
  • Applies to: all elements
  • {{ Xref_cssinherited() }}: no
  • Percentages: N/A
  • Media: {{ Xref_cssvisual() }}
  • {{ Xref_csscomputed() }}: absolute length; '0' if the border style is 'none' or 'hidden'

Syntax

border-bottom-width: border-width   or
border-bottom-width: inherit

where:

border-width
Is either a non-negative explicit {{ xref_csslength() }} value or a keyword denoting the thickness of the bottom border. The keyword must be one of the following values:

 

thin   A thin border
medium   A medium border
thick   A thick border
The specification doesn't define precisely the thickness of each fo the keywords, which is therefore implementation specific. Nevertheless, it requests that the thickness does verify the thin ≤ medium ≤ thick inequality and is constant on a single document.
inherit
Represents the calculated value of the {{ cssxref("border-botton-width") }} of the parent's element.

Examples

{{ CSSRefExampleLink("border") }}

element { 
    border-bottom-width: thin;
    border-bottom-style: solid;
    border-bottom-color: #000;
}
