Have you heard of these HTML elements?

I was familiar with all of them except for the tag. In fact, I use fieldset, optgroup, legend etc on all forms I create nowadays and have done for about two years. The legend thing is a pain in the arse to style in a way that will be displayed the same in all browsers if you want to do anything advanced.

They're really minor things, Malodia. Lots of us haven't heard of all of those! They are relevant now (except for which isn't supported by Internet Explorer yet).

Yikes. I've never heard of any of them. Are these things that I should know? Or just code curiosities that don't really relate anymore?

I had heard of awhile back, and only about a week or two ago. The rest were news to me!

I took a peek at my html site (which I haven't done for a long time) and some of the tags weren't IE/Netscape friendly back 3 years ago, the following didn't work:

Tag Internet Explorer Netscape
abbr No 7 up
acronym Yes 7 up
fieldset Yes 6 up
label Yes Not properly in NS7
q No 6.2 up

Was tested back then on IE5.5 and NS 6 & 7 - mozilla wasn't big back then and Opera support was very limited

They are html 3 tags I believe, very old anyways.
A lot of these, although good do have their downfalls, the abbr for example leaves a dotted line under the word which displays differently in different browsers to an extent it can confuse people, and the CSS dorks often change the cursor for it making it even more confusing. as title= can now be used on just about anything the abbr and acronym can be replaced with span (CSS takes over again)

I remember using address back when I did my html site, it didn't work in all brosers back then. is same results when using , although it does help a screen reader as the 'address' is said, like the and tags

Does Opera support fieldset/legend now? up to last version they never did and mozilla had real up and down support for it back in '03 (I mentioned that on my html site on mells. page)

label is another that should be in that list, is very useful for accessibilty but often overlooked

the is a dead tag almost, without css all it does is place quotes around the text, span is better off being abused than q

The only ones I know about were /. The rest is new to me.

Quote: I don't really get . What's the use? This can this be done with a single as well, right?

Search engines probably use(d) it to add places to their local searches (I have no evidence to support that, but it seems logical.) It can be done with a div, but you have to set a class, just styling the address tag would be shorter.

I've heard about and before but never used only

I hadn't heard of and before.

But I really like , indeed a gem!
