border-left-width

Summary

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

Syntax

Formal syntax: <br-width>
border-left-width: 10em    /* Any <length> value */
border-left-width: 3vmax
border-left-width: 6px

border-left-width: thin    /* A keyword */
border-left-width: medium
border-left-width: thick

border-left-width: inherit

Values

<br-width>
Is either a non-negative explicit <length> value or a keyword denoting the thickness of the left 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 follow the thin ≤ medium ≤ thick pattern and is constant on a single document.
inherit
Represents the calculated value of the border-left-width of the parent's element.

Examples

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