Curing the Jet Blues. (For anyone curious, the reason JetBlue actually got a lawsuit was because they didn't bother with all the other stuff that could have prevented it, like all the meetings scheduled with them etc)
Anyway, interesting for those making sites as complicated as JetBlue's.
He does make a mistake: setting :active will NOT set the focus for IE7, only IE6... IE7 "fixed" the :active "bug" of affecting :focus. The link to the Sitepoint reference only points out that :focus doesn't work in IE7 or 6. Default outline will work, but to set :focus styles in IE7 you'll need something like Peterned's whateverhover3 or something.
