There's no longer one type of browser, on one operating system. Your website may look perfect in Windows Explorer, but a mess in Firefox, and unaccessable in Opera, thus I encourage you to down load the major browsers and view your site with them. You may also want to test your site out on different systems (i recommend you check it in WIN 98 because it is still widely used) If you want everyone to be able to access your site, it should only require an HTML compatible browser to view, and not dependant on cookies or javascript. This does not mean that you should neglect new technology, use it, but give an option for those who do not have it. Also validation is important for cross-platform compliance, and good structure. Here are some links that may help...
