/**
 * 
 *    'border-left-width'
 * 
 * 
 * Value: thin | medium | thick | <length>

 * Initial: 'medium'

 * Applies to: all elements

 * Inherited: no

 * Percentage values: N/A

 * 

 * This property sets the width of an element's left border. The width of the
 * keyword values are UA dependent, but the following holds: 'thin' <= 'medium'
 * <= 'thick'.
 * 

 * The keyword widths are constant throughout a document:
 * 
 * H1 { border: solid thick red }
 * P  { border: solid thick blue }
 * 
 * 
 * In the example above, 'H1' and 'P' elements will have the same border width
 * regardless of font size. To achieve relative widths, the 'em' unit can be
 * used:
 * 
 * H1 { border: solid 0.5em }
 * 
 * 
 * Border widths cannot be negative.
 *
