Awesome.

As Paul Irish put it, ‘Some of the finest research and writing about HTML & CSS & JS.’

‘There are some particular findings that are pivotal to issues such as readership and readability and comprehension, which is really what body copy is all about. If people won’t read it, or if they can’t read it or understand it, then what’s the point of having it?’

‘This is a simple trick to overlay a grid or a mock-up over a page you're styling. It will also allow you to edit content directly in the browser to see how your layout behaves depending on various lines of text.’

Looks at your CSS and tells you what's wrong with it.

Deep inspection of hasLayout, the cause of most 'IE bugs'. Last updated 2008.

Return to this. A good set of standards, including some things that I wasn't aware of and would like to implement.

“Lifted corners, Curled corners, Perspective, Raised box, Single vertical curve, Vertical curves, Single horizontal curve, Horizontal curves, Rotated box”

Sounds stupid and listy but it's actually a good introduction to some of the more useful and practical pieces of the huge insane HTML5 Boilerplate (html5boilerplate.com).

How to make an background image scale without using a ton of JavaScript.

What 'the web' actually is, and why building desktop-class applications on it is not what it was built for.

Using CSS to detect device size (for things like iPads and iPhones).

This may be worth looking into. I waffle on whether this sort of thing is ultimately a good decision — you're relying on someone else's framework, it takes a while to learn and master, and once you decide to go with it you're essentially stuck with it. But isn't that the case with any pseudo-framework developed for a website design? I should test this on a little project.

As seen on Normative.com.

This could be good. "Cufón aims to become a worthy alternative to sIFR, which despite its merits still remains painfully tricky to set up and use. To achieve this ambitious goal the following requirements were set: No plug-ins required; it has work on every major browser on the market; no or near-zero configuration needed for standard use cases; it has to be fast, even for sufficiently large amounts of text. And now, after nearly a year of planning and research we believe that these requirements have been met."

Invaluable for troubleshooting web development in IE. Wish I'd known about this before today!
