I know absolutely nothing about CSS but might like to learn, particularly because there's an effect I want to add to my site and would like to know if it's even possible with CSS.
When I go to Custom Design I'm not able to get the free preview of CSS to work. In firefox sometimes the "welcome to custom css" box where you replace the code is blank, and sometimes it's ok. In iexplorer it always shows up - but in either browser whenever I replace the welcome message with the CSS I am trying to experiment with, it says 'saving changes...' for a very long time and never gets past that.
What I am trying to do in particular is to create some kind of hover/mouseover effect over images. I would like the images to be links to other pages, and ideally I would like to have the image change to another image, but I would settle for it even greying out or highlighting or some other way for the viewer to know it is a link. Some of your forums say that this can't be done at wordpress because that's a java function, but many, many tutorials out on the web say that it can be done completely in CSS without java. I'd really like to try to play around with it first and get a sense of whether or not I feel capable of learning CSS, before purchasing the upgrade.
Any information you can give me about the CSS preview, and whether or not I would be able to accomplish any kind of mouseover effect with an image that is also a link, would be greatly appreciated!
