As probably all web developers, I have been stuck with this problem for quite a while: how to make two columns equal height (to draw a line between them, color them, .. whatever).

First I used the most popular margin:-value, padding:+value technique, but quickly discovered that internal anchors are not working. Further internet researching has shown solutions so huge and so hacky (pure CSS abuse), so I just wrote these two lines of jquery code to make both columns equal height. All of the problems (bottom border, anchors, margin/padding weirdness) disappeared instantly.
