/**
*
* 'border-width'
*
*
* Value: [thin | medium | thick | <length>]{1,4}
* Initial: not defined for shorthand properties
* Applies to: all elements
* Inherited: no
* Percentage values: N/A
*
* This property is a shorthand property for setting 'border-width-top',
* 'border-width-right', 'border-width-bottom' and 'border-width-left' at the
* same place in the style sheet.
*
* There can be from one to four values, with the following interpretation:
*
* -
* one value: all four border widths are set to that value
*
-
* two values: top and bottom border widths are set to the first value, right
* and left are set to the second
*
-
* three values: top is set to the first, right and left are set to the second,
* bottom is set to the third
*
-
* four values: top, right, bottom and left, respectively
*
*
* In the examples below, the comments indicate the resulting widths of the
* top, right, bottom and left borders:
*
* H1 { border-width: thin } / * thin thin thin thin * /
* H1 { border-width: thin thick } / * thin thick thin thick * /
* H1 { border-width: thin thick medium } / * thin thick medium thin * /
* H1 { border-width: thin thick medium 12cm } / * thin thick medium 12cm * /
*
*
* Border widths cannot be negative.
