not serving css styles?, css not showing up on local dev box

Win98, Apache 1.3.20, PHP 4.06. I realize this isn't an Apache forum but you folks are a very helpful bunch and PHP and Apache are like peas in a pod so I though I'd give it a try here. My CSS styles don't display on my dev box but they show up just fine from my web host. In other words, the assigned font style for a link is verdana, black, 9px, no underline. At home it shows up as the default Times New Roman, black, size 2, blue underline. But when uploaded and served from my web host it displays properly in any browser. My default browser for development is Mozilla but the same problem occurs when I try it with IE6. That makes me think it's an Apache config thing. I've searched all topics in a couple of forums and the Apache.org docs. Does anyone have an idea? Thank you for your indulgence. Jim
