As to obsolete or unused styles:

-- safe to remove:
.copyright - seems to be a remnant of something that was originally in the page footer; not found in use anywhere
.highlight - can't find that anywhere (I've been abusing it in my own preliminary code but should use a better class name)

-- doubtful (investigate):
.comments - I suspect this may be intended as an easy way to control whether or not to show comments; maybe we should look at the current code (in handlers/page/show.php) to see if this could make things simpler or not

-- do NOT remove:
.editornamecss - used by the WikiEdit script to style the name of the editor in the toolbar (the class name is passed as a parameter)
.pagenote - used to markup the edit note in the recent changes view.

.highlight isn't used because there is no highlighter in the formatter. I suggest "!!" for it.

There is a IE related bug in the CSS's I tried so far.

IE does not allow font-size's to be changed that have been specified with units of pt or px's. This in effect makes a site just have one default font size for everything and when you try to increase the font from View->font-size nothing happens.

I suggest to CSS designers (or modifiers) not using pt or px with font: or font-size: css tags, working with % or em's is a better solution.

I made a small modification to the original wikka.css and essentially change the BODY font-size and the p,td ... font-size and the drop the .page font size and then the site can have fonts that increase and decrease in size even in IE.

I'm working on adding a side menu using CSS (static side menu and removing the top menu) for an alternative style sheet (using it on my test site). The question I have is where the heck are the divs that call the stylesheet? If I can't find the html/php that calls the wikka.css, how do I alter it? Any help is appreciated.

DevNet, the divs for a page are distributed over some files. This will be changed in the future but not in one of the next versions (see http://wikkawiki.org/WikkaSkinOptimization). The stylesheet is included in actions/header.php

Thanks much. Wow...there really is a need to optimize on that. It's pretty tough to get this to do what I want it to.

We have a dark colored header and a white page background. Since the same css currently controls the link colors in both places, we either get links that are too dark to read in the header or too light to read on the page.

Is there a relatively simple way to separately control the color of the navigation links in the header from those on the page?

FrankK,
.header a {(put your definitions here)}
.page a {(put your definitions here)}

That should work (even with IE)

That was just too easy. I had tried something similar, but must have messed up the syntax somehow.

Thanks very much!

I'm playing around making a World of Warcraft Guild site for a friend (no Skins that I could find, so I made one). Everything looks good so far except the right float doesn't stretch the page as it gets taller (the Vent server can get between 20-40 ppl on it at a time). Any thoughts as to what could be causing this and how I could fix it?

Thanks,

to clear floats you should add ::c:: in the page

Awesome - thanks! That worked perfectly... CrystalWoW skin should be OK for prime time now :)
