Linking with #

Ok this is so noobish, but I can't think of how to use # to link on the same page.
For instance,

<a href="#blah">

HTML:

Now what would i put where that blah section is on the page?

I haven't done anything like this in quite a while and I can't remember what its called to look it up. Thanks.

Would link to

But nowadays (and especially if you're using XHTML where name is deprecated on all but some form elements) you should link it to an element that has an ID with a value equal to your href.
