Did Firefox exist when this thread was started? ;-). How about any of the original people commenting in this thread?
IBACFII, welcome to web design. You're very lucky to be designing pages in the present. 2.5 years ago, when this thread was made, things were a lot different. Standards existed, but to a large extent they weren't followed till MSIE 5 and Netscape 5. Although most people used MSIE 5 or 6, there were quite a few people who used Netscape 4.x and MSIE 4.x. I don't know if you've ever tried to use either. Neither of them followed the standards, but what's worse, they both had their own, different standards that they followed. Websites designed according to the standards adopted in MSIE/Netscape 5+ didn't always display correctly in previous versions. In fact, we often had to use incorrect code in case someone was using an old browser. In August of 2002 (when this whole browser-support issue was relevant), there were still 10.5 million people (or page loads? I'm not sure what these statistics are) using Netscape 4.x. Combined with another 9 million using MSIE 4.x, that was just too many people to exclude. So we were often forced to use JavaScript to see which browser was being used and then display different code to different browsers. Thankfully that's not the case today. Only a total of about 180 thousand people use MSIE/Netscape 4.x anymore. Of the browsers that are used, almost all are standards compliant. You're right. If the code's valid, that's pretty much all it takes nowadays. Pages designed with CSS even work now. Before, being able to use css instead of tables was what many considered to set the good designers apart. However, many browsers weren't even able to correctly process the css code to display the page correctly! You rarely see that problem today. Things have certainly come quite a ways. And to be honest, I'm suprised how long it's been. It seems like only a few months ago I was just learning html. But it's been over three years now since I first signed up to be able to post my questions.
Just for reference....
