Dave Gash, a great friend of mine and a terrific conference presenter on user assistance, has written an article on how to add fading tooltips to HTML links — the sort of thing that’s ideal for presenting little snippets of help (aka user assistance) to users as they are filling in a web form, for example.
His step-by-step article is here: http://www.writersua.com/articles/fadingtooltips/index.html.
[Dave has been a technical writer and online Help author for years, but originally comes from the world of programming (though we don’t that against him!). So he’s really good on all the ‘techie’ stuff and has a knack for explaining it to novices so they understand. Dave’s currently available for hire — you can contact him at firstname.lastname@example.org.]
