Cross-Browser Compatibility Checking

It’s a good idea to test your site with multiple versions of multiple browsers, particularly if you plan to do anything fancy with style sheets on your site. This doesn’t mean that you have to support all browsers – for example, the pages on thesitewizard.com do not work well (if at all) under IE 4 and Netscape 3 (and earlier). However, when you are able to test your pages this way, you can at least reduce the number of problems your pages have with the different browsers.
The tips in this article allow you to test with multiple browsers even if you have only one machine.
