Values
<line-width>
-
Defines the width of the border, either as an explicit nonnegative
<length>
or a keyword. If it's a keyword, it must be one of the following values:thin
medium
thick
Note: Because the specification doesn't define the exact thickness denoted by each keyword, the precise result when using one of them is implementation-specific. Nevertheless, they always follow the pattern thin ≤ medium ≤ thick
, and the values are constant within a single document.
