Have in what sense?

What if the style were:

  <span style="border: 7px dashed red; border-right-color: green">

What should happen then?

>> Given this example :<div style="border-width: 1px 2px 3px
>> 4px;"></div>. What would be the length of the style for the div?

If the style were:

   <div style="border-top-width: 1px; border-right-width: 2px;
               border-bottom-width: 3px; border-left-width: 4px">

should the length still be 5?  Why or why not?  Note that .cssText on 
that div will return "border-width: 1px 2px 3px 4px" in some UAs and the 
expanded version in others, but UAs tend to have the shorthand and 
longhand form return the _same_ thing for .cssText.
