22881 - the combination border-style double and thin width does not work

Status: VERIFIED DUPLICATE of bug 1781

(Core :: CSS Parsing and Computation, defect, P3)

Description

[Thomas Jespersen]

If you look at the above URL, the paragraph should have a double, think border
set with this stylesheet:

border-style: double;
border-width: thin;

the border does not appear with the latest "nightly" build on a linux system. It
does however seem to work with Netscape 4.7. If I try other values for
border-width, the border will appear correctly as a double style. If I try other
styles with thin width, everything will be ok. It seems to be just this combination.

According to the spec, the sum of the two lines and the space between them must
equal the value of 'border-width'. Since you set the border width to 'thin' which
is 1 pixel, we get 1/3rd of a pixel for each line and the space between so
nothing gets displayed. When using a 'double' border, you should set the width to
a minimum of 3px or 'medium'.
