Attribute for <A ...>
TITLE = "text string"

W³C says that TITLE is "an advisory title for the linked resource". The idea is that TITLE gives a description of the linked resource that is more informative than the URL.

Check out <A HREF="deniseres.html" TITLE="Denise Dodd's Resume">my resume</A>	Check out my resume

Most browsers have ignored this useful attribute. One that doesn't ignore it is Opera. Opera displays the value of TITLE in a small box when the pointer is over a link. The latest version of MSIE also shows a little box over the link, but otherwise ignores TITLE.

Opera also uses the value of TITLE as the subject line in email links:

Send us <A HREF="mailto:[email protected]" TITLE="Response to Web Page">feedback</A>	Send us feedback

It's worth noting that the ability to indicate a subject in an email link is one of the most often requested features that Netscape and MSIE have ignored. Hopefully they will catch up sooner or later.
