I said I'd report back. I've now taken delivery of my $30 "Browser book" for client-side web developers, and I have to say I'm delighted with it.
http://www.visibone.com/products/browserbook.html It's 18 pages of dense info on javascript, DOM, CSS and HTML, plus extras like fonts and colors, profusely color-coded with info signifying things like: doesn't work on Firefox/IE; poisonous; confusing issues; astonishing diversity; unsettlingly advanced. It looks to me like the dream spec of a web developer-cum-presentation expert who eats his own dog-food. The coil-bound pages are printed on card, and I wish now I'd paid a little more for the laminated edition. I know all this info is available on the web for free, in a multitude of different formats, but it's the convenience. People who write web-pages all the time doubtless know it all, and may even feel that (convenience)=(on-line availability). I literally pick it up now and again and it takes me a day or so to think myself back into it. This visual-aid will speed up the task. It promises to become more useful the more I use it. The only caveats are: -- The copyright notice: 2009. But when I actually come to hit out-of-date info, then's the time to go surfing the net, I guess. -- I need a magnifying glass to read it reliably. But hey! - this is all about compressing essential info onto a few sides of US-Letter/A4.
