I’m with you. I make it work in FF and then make adjustments if it doesn’t work in IE, but usually it works.
I have basically abandonded no-table layouts for a while as it’s a hassle to get them to work right, and backwards compatability is pretty bad.
But using strict html, table layouts, and proper css usually works without a lot of fuss in FF, Opera, and IE. Netscape is a dead browser and pointless to work with, imo. 4.7 is useless and I pity anyone who still uses it, they couldn’t make up there minds between 6 and 7.
If it looks good in Firefox, it should also look good in Safari and Opera.
