1. A mention of the box sizing model ( which is imo the core of CSS )
2. Following that, a mention of the double margin IE bug. Nope; but there was vague mention of browser differing in spacing.
3. Mention of the fact that nothing can be changed because browser vendors don't get along and refuse to change stuff in any meaningful time-frame regardless of the specs. Wasn't disappointed.
4. Mention of SASS/LESS. It's there.
5. A statement along the lines of "CSS is obviously wonderful because it's still around. It will be around forever." Got it.
6. Mention of the need for a way to do paging properly. Yay.
Pleasantly surprised by:
1. Mention of the Acid tests.
2. Mention that single line comments are desirable. Why still not there???
Unhappy with: Hatred for IE conditional comments, web fonts, and the video tag. ( but confused since he advocated for both web fonts and the video tag?? )
All in all an interesting read.
