Information on Border Slants (via Paul Hammond). Border slants are the effect whereby diagonal lines can be created using pure CSS, by taking advantage of the fact that thick borders around a box meet at an angle. This article describes the effect in detail and shows how it can be used to achieve a number of interesting shapes, then goes on to show off with an impressive Valentine’s Day Heart.
