The worst mistake a developer can make is not using a doctype. This sends IE into "quirks mode" where it uses a different box model and has many other problems. This is simple to fix, you can even use the HTML5 doctype to trigger standards mode: <!DOCTYPE html>

The second major bug is the double-margin float bug. When you float any element and apply a margin, it is doubled in IE6. You can fix that by adding display: inline to that element's CSS.

(Note: This question may be better asked - or already have been asked - on Stack Overflow.)

I wrote an article a few months ago for common IE6 bugs: Ultimate IE6 Cheatsheet: How To Fix 25+ Internet Explorer 6 Bugs. It'll help for some IE7-specific bugs as well. There are more resources at the bottom if you need them.
