I still don't see a white line (1900px window). (How can there be one, the background is white.)

A <p> element cannot contain another block-level element. A <p> is implicitly ended when another block-level element is encountered. Add the colours to the <ol>s directly.

Don't use frames; use CSS.

The first step is always to validate your page and correct any HTML and CSS errors. Your page has 551 HTML errors:

I think that's because Geocities inserts a line before your page.



I don't think that matters, but there's no reason to...

This is what I see in FireFox:

There are also many validation errors on your page. Some of them may be unavoidable on Geocities, but they probably...
