As a web programmer, CSS is (IMO) one of the most useful things one can know when it comes to websites. Short of learning one of the programming languages, they are the best way of getting what you want to happen... to happen.
I was curious, however, how many people here (who have experience) use CSS in their websites? I often use it for clients, but what about you other people?
It's true that it is much more complicated than basic HTML, but it is also much more useful. If you actually do want to learn it, the best place to find links is at http://www.w3.org/Style/CSS/learning - it's a great site!
I like the css in my php forum but I get way too confused when trying to put it on my html website. I had downloaded html template that used a css sheet and I was not able to use it because I do not have enough knowledge. I have a book for dummies and trying to figure this out, not enough time it seems.
