ISSUE-26: Percentage values on 'border-width'

% border-width

Percentage values on 'border-width'

State:
CLOSED
Product:
CSS3 Backgrounds and Borders
Raised by:
Bert Bos
Opened on:
2008-04-04
Description:
'Margin' and 'width' allow percentages (of the containing block) and the Box module proposes to extend 'padding' with percentages as well. If only for consistency, it would make sense to allow percentages on borders, too.

The current draft defines 'border-width' that way: <length> | <percentage> | thin | medium | thick

Note that percentage borders wouldn't work very well in cases where percentages can't be resolved.

Related notes:

Defining percentage borders is complicated for tables
and would require defaulting to some value (medium?) in cases where the
percentage cannot be resolved. Since we have no compelling use cases
for percentage borders, we plan to drop percentage border-widths in the
next draft.
