Hi all,
jQuery originally had a "Try jQuery" thing that was mostly for beginners and assumed a fair bit about knowing CSS, plain JavaScript and HTML.
Today they re-launched[1] with Code School and it is pretty impressive, I highly recommend it.
It goes through understanding the DOM, cross-browser differences, CSS, the jQuery API and more. And does so in a very easy to understand way, with videos, downloadable slides with exercises a long the way. Yet, all-in-all, the entire course shouldn't take more than a couple hours to complete start to finish.
While Trevor, Roan and I are still working on taking our experience from the "Frontend Master Class" and putting it out there in a re-usable way, I'm thinking of dropping a few chapters in favour of this and refactoring the other chapters to be more like this.
So, go check it out: http://try.jquery.com/ !
Happy weekend,
-- Krinkle

PS: I meant to send this out earlier (like, relative soon after jQuery's blog post) but I figured i'd check it out myself first. I have done so now, and still recommend it :)
