Divs

Hi
I am coming here with a newbie-question.

Sometimes I see in Css-codes that peolpe put div before their names. like

div#header { filling:out}

Why is that div there, isn’t it enough to have it in the html file?

uhm sorry, the forums were totally crapping out just now.. what I said was: as you said, that’s unneed. any ID should only ever occur once per page, so the tag name doen’t add any information.

Ok thanks. The thing is that I have seen it on many of Chris Coyier’s screencasts. Seems weird that such a well educated css artist write inappropriate code

With IDs it make no sence, but with classes it can be very helpfull. For instance:

You have a class named highlight. If it is an h1 element you want a yellow background, but a highlighted span tag should have only a yellow text color. In CSS you do this:

h1.highlight     {  background: yellow; }

span.highlight  { color: yellow; }

But with IDs it is better to use only #idName, because this is faster.
