Somebody tell him to keep his hands off his template
I'm not going for the mutating-color template this time, but a very nice CSS-based template I found at BlogSkins. You can see a preview here. (BlogSpot's banner ad doesn't seem to like CSS, but it doesn't matter: That's just a temporary blog to show me what the page will look like.) The original was white with green and lavender boxes, but I decided to keep my current color scheme, mostly. When the ad isn't present, the pale yellow boxes to the left slightly overlap the darker title banner. Kinda cool.
Unless somebody says "God, no!", I expect to apply it to this page soon.
Advantages: The page should load faster. Disadvantages: I'll be forced to learn CSS.
LATER: You have to write extra code to allow what plain old HTML already does: Allow the person viewing the page to change the size of the text. I haven't found the advantage of this yet. (Unless the point is to prevent them from doing that and screwing up your layout.)
