XHTML - create my own elements?

Mr. Flibble

Can you have your own elements in XHTML?

Say I make up a tag <mytag> so I can easily modify its properties using CSS, do I have to tell the XHTML somewhere that I've made this tag, or is it just not allowed?

what you're looking for would be classes in css.

xHTML doesn't allow the making up of your own tags.

Mr. Flibble

Ah, right. Cheers.

Best give a <div> tag an id and then in css, you can use #whateveridis to modify it's properties. Similar to classes but id's are unique to one element and classes can be applied to multiple elements on the one page.

Mr. Flibble

I want to control the style of a number of elements (for questions and answers in FAQ here) so using class is best right?

While we are all here, can somone verify the following for me.
- one or more elements can have the same class name but only one element can have a particular ID?

- to access an ID in css you use #theid and to access a class you use .theclass?

- and to only specify particular id classes you would do #theid theid2 or #theid theclass2 for IDs and theclass.theid or theclass.theclass2 ?
So a space for IDs and a . for classes?

Use XML and a dtd to make your own elements.

For the FAQ section, you could use something like this:

[html]
<style type="text/css">
dt
{
/* same definitions as your question class */
}

dd
{
/* same definitions as your answer class */
}
</style>

<dl>
<dt>Your question here</dt>
<dd>Your Answer here</dd>
<dt>Another question here</dt>
<dd>Another Answer here</dd>
</dl>
[/html]

I think this might make better / more semantic markup as it associates a question with an answer, while using <li> tags doesn't.

Mr. Flibble

Ok, I tried to do that. Can I put lists inside the answers tho? I seem to get errors when I do.
