I first met Alex Homer in 1996/7 when he'd just finished writing his HTML 4 book. Or two books, because there was one for IE and one for Mozilla. Yes, the browser incompatibilities were pronounced even then. Nowadays browser compatibility is better, but still not solved, and those of us in the Web space can spend considerable amounts of time trying to get web sites working in all browsers. Coding against multiple browsers simultaneously is problematic, so we tend to work in one, and then test in the others, which is where arcane knowledge and debugging skills come into play. It's a constant cycle of tweak, save, alt-tab, F5. Rinse and repeat.

Nicole Sullivan has just written a good blog post on debugging CSS, which is worth a read even if you don't have any explicit CSS problems. Read it at http://www.stubbornella.org/content/2012/05/02/cross-browser-debugging-css/
