Make bubble help appear when I hover over a link

Question

I have seen some web sites where bubble help appears when I hover over a link.

Can anyone tell me how this is done? I would love to do this for my site if it would not add too much to the bandwidth needed.

Answer 1

use the Title attribute in the href tag

eg

<a href="http://www.website.com" title="Website name">Website Link</a>

a Tool tip with the title contents will pop up

Answer 2

Take a look at tooltips, for example: 30 jQuery tooltips.
