No Styling at All?
If you see these pages in really boring fashion — everything left justified including headings, no color at all except links, and so forth — then your browser does not support CSS style sheets (version 3 or lower browsers), or its support of CSS is so buggy that I have hidden the style sheets from it (version 4 browsers) — trying to code around MSIE 4.x and NN 4.x CSS bugs is a nightmare. You do not need to upgrade your browser! The content should still be accessible to everyone in any browser, even if the formatting is not. If you do wish to enrich your browsing experience on most sites, I have a recommendation, but it’s in no way a requirement. One other possibility, if you have a version 5 or later browser but you’re not seeing any of the styles, is that your user settings have disabled style sheets. If that is the case, you might want to re-enable style sheet support in your browser’s user settings.
