Thanks to these wonderful people, they've made things so much easier for me. I can now change the fonts, the backgrounds, everything, by altering one file.

I've got a problem now. I updated the css file, but for some reason, GeoCities insists on using an old one that was supposed to be overwritten.

Way to go. I'm in the process of converting from table to a pure CSS layout. Ugh, the data transfer is time-consuming, but CSS is oh-so-more flexible.

I think I see your problem. From your Benifits of Nuclear page:
The way CSS works is that the last line read takes precedence. Therefore, since the Geocities CSS file loads up last, it rules.

Beat them at their own game. Put your CSS link (<LINK REL=STYLESHEET HREF="../fissionstyles.css" TYPE="text/css">) in the next line down.

Now you're suppose to put the CSS links in the head and this'll move it to the body, but... that's where they went. Just make sure you put it in before any layout or text code.

Hey look! It's now updated. It obviously just takes some time for some stupid reason.
