"Whoops!"

[Draknek]

The cynicism! It's killing me!

CSS is an excellent tool for certain tasks. Most notably, any time you want to style the appearance of more than one object at a time. For these things, you can do it in HTML, but once you've learnt CSS it becomes a lot easier.

HTML is also a good tool for other tasks, but for the most part, as good a tool as CSS. If you know CSS, you can use it. If you know HTML, you can use that. It's personal preference.

The only place I can think of that HTML is easier to use than CSS is tables. Now, I can see some argument in the idea that you shouldn't use tables for presentation (have you ever looked at a website in a text-mode browser?), but at present, table-less designs are too much effort to be worth-while for most.

With a website of any decent size, most of it falls under "making everything look consistent".
