As far as Ids replacing Names. I'm fairly sure PHP forms still rely on names?

Yeah they do.

As you can see, I've edited my first answering post (with achnowledgment) to include any additional information we brought up about the differences between using id and class in CSS.

Considering how the topic was getting quite lengthy, I thought this might be wise for when somebody else finds it!

Am I right in thinking that it is not possible to declare child selectors from a class?

eg :

.content h1
.content h2

Normally I would use DIVs to do this, eg :

#content h1
#content h2

If so, then is it bad for me to be using more than one instance of a DIV within a page?

I have a text box that I would like to use multiple times around the page, and it needs to use different styles for a and a:hover within this text box etc, but from my understanding this cannot be done with a class...

Actually, you'd be wrong; you can very nicely use that selector.

It is only bad to use multiple instances of a div, on the same page, if that div has an ID. If you could give it a class, instead, then you're ok.

I do believe, if I understand you correctly, this is a case for multiple attributes, like so:

CSS:

.textBox {property:value;}
#commentTextBox {property:value;}
#formTextBox {property:value;}

xhtml:

<div class="textBox">...content...</div>
<div class="textBox" id="commentTextBox">...content...</div>
<div class="textBox" id="formTextBox">...content...</div>

This will allow you to specify common styles that all of these boxes need to have, via the class "textBox", and then separately, individual styles each box needs to have, via their respective ids.

Yeah they do.

It has not be depreciated for the input elements, but it has for the form element itself. [As well as, a, applet, frame, iframe, img, and map. cite: http://www.w3.org/TR/xhtml1/#h-4.10]

Personally, I only use classes unless I need to bring in JavaScript or targets. As older versions of Netscape handle classes much better than ID's with regards to CSS styling, I don't see a reason to use ID's for things when <ul class="nav"> works just as well as <ul id="nav">.

Brilliant - thanks all, especially Herks, that's cleared it all up for me. Think I learnt it in some kind of backward way, but now is bright and clear

Well, I see your point, and I'm sure I'm just being nit-picky in saying this, but using IDs for a singular element on a document is just semantically correct.

It would be like going to college and being handed a class card instead of an ID card; there truly is only one Ryan Fait in that school, but what the heck, the administration thought it best to put you in your own class of people... all by yourself.

Haha, nice analogy. It is indeed true, but I also like the look of a period much better than a #

I think you can use the id class for say your header, footer etc (as they only appear once in your page).
