i've been working (more accurately trying to work) on the TOS Funerals website design so it works well in older browsers, because it degrades horribly in them. for this to work, i needed a technique to force a footer to stay at the bottom of the window whether or not the content filled the window. the first technique i tried was from Boagworld. it worked like a charm - but only in newer browsers (Chrome, Firefox 3, Flock 1.2, IE 7, Opera 9.6, Safari 3/Win). it completely failed in IE 5.5 and 6 (quite unlike the advertisement. my guess is IE 5.5 and 6 don't understand the conditional comments).
Update: the fault was with me. the Boagworld technique works. quite well, in fact. and it's smaller in both markup and styling.
