HTML and CSS Reference
Hey! It seems like half
of CSS3 is really CSS 2.1.
It's all the work of the same
group at the W3C.
CSS2 had to be fixed before
they could move forward.
What's taking so long?
CSS2 became a standard under
the old process, Now two
implementations are needed.
But even IE8 supports CSS 2.1!
The W3C had to wait for a library of test
cases; we need to be able to test
whether browsers meet the standard.
AH! Because it's no good just
saying you meet the standard;
you need to be able to prove it!
Exactly. The CSS 2.1 specification
finally became a W3C
recommendation in June 2011.
Now that the history lesson is out of the way, the rest of the
appendixes are targeted at taking a complete novice at web
development and giving them enough knowledge to appreciate the rest
of this topic. They also constitute a useful refresher course for more
experienced web authors. First you'll learn about HTML itself.
