I'm new to XOOPS, and hope to give theme making a whirl soon (after I'm a bit more comfortable with admin and playing with modules *S*). I've downloaded quite a few themes made by others...THANKS to the theme makers 8^)

I do hope some have no tables. I've done it before with MT, but it was a struggle LOL (and I had to resort to a table for my comments area...grrr). Maybe I'll get it down better then 2nd time around. But if there's one that already is pure css (hopefully with a relative width div for the center section), I'll probably use that to start off with.

When I do get into editing some of the CSS's, the first thing I'll do is change all px/pt's to keywords.

Quote:
By using pt/px, IE is *NOT* able to increase font size. Using keywords or em's (harder to use as far as I'm concerned) enables IE users to increase the font size so that they'll be able to read a page. With relative font sizing, viewers with normal vision won't have to suffer reading large text, while visually impaired viewers will be able to increase the font size in IE.

With the numerous combinations of screen resolutions, monitor sizes, and viewers' visual difficulties, I see no reason to take a chance on viewers not being able to read a page if they choose to stick with IE. Many of my friends are older, and have difficulties reading some sites, and prefer sticking with IE. As for printing, use a print.css.

Hopefully when MS comes out with a new browser, it will have zoom text capabilities like Mozilla/Firebird. Until that time, I'll use keywords (or perhaps learn em's better).
