There are some seriously messed up things with absolute positioning in IE 6. I struggled and struggled tonight trying to get a logo to sit in the top left part of the #wrapper div:
#logo { position: absolute; }
#wrapper { position: relative; }
The logo was just not there. I ended up putting it in one of the main content columns, and it showed up in the right place (luckily, it also works in other browsers as well that way).
I couldn’t find much, if anything, useful about this behavior. Why do I always have some trouble with absolute positioning? Why aren’t more people blogging about this? Absolute positioning is supposed to be so easy that it’s considered cheating.
