Syntax

border-right-width: 10em;    /* Any <length> value */
border-right-width: 3vmax;
border-right-width: 6px;

border-right-width: thin;    /* A keyword */
border-right-width: medium;
border-right-width: thick;

border-right-width: inherit;

Values

<br-width>

Is either a non-negative explicit <length> value or a keyword denoting the thickness of the right 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 rule thin ≤ medium ≤ thick, and is constant on a single document.

inherit

Represents the calculated value of the border-right-width of the parent's element.

Formal syntax

<br-width>
where 
<br-width> = <length> | thin | medium | thick

      <td id="b4" class="blu">
