Does anyone know how people make those ever-changing backgrounds, the ones in which say, you have an intro page with a simple Enter Site and a logo on it right in the middle, and then a radial gradiant for a background. And SOMEHOW, you won’t ever see scrollbars on that page, no matter what the resolution of your monitor is, and yet the gradiant stays the ratio?

I dont know what they do at all. A large image and then scaled down doesn’t seem like a plausible solution, seeing as a person with 800 by 600 on 56k downloading a 1680 by 1050 image doesn’t make too much sense.

Another sort of side and distantly related question, imagine a plain Enter Site image on a page, with a black background. Horizontally centering it is trivial, with \<center\> but how does one vertically center it? \<vcenter\> isnt a tag, although I wish it was. A solution to this problem is probably make a single celled table and then tweak the cell alignment properties. But still. Can’t do that with an ever-changing background I should think.
