Nice. To avoid the annoying type-to-search feature, just search for "a" and get the whole document at once:

http://instacss.com/#a

Edit: ugh, that doesn't actually work. It only gives you p-z. Hey instacss! Please provide us with a link to the actual document. Preferably in plain HTML so we can download it. Alternately, anybody care to scrape this thing and post it in full?
