Mario Heiderich of Ormigo has created a jQuery based code snippet/bookmarklet that is capable of detecting floating errors and adding a dotted orange border to elements which should be cleared - but aren't. It saved me a huge bunch of time debugging complex layouts for all browsers - especially IE6. If jQuery isn't already loaded Read the rest...
