Issue 340

The news from browsers keeps on coming, with new CSS features landing in all three major engines each month. I've linked to some of those features and announcements this week.

Also, not CSS but very related, we published the remaining modules in our huge Learn HTML course today. As I mentioned in the announcement post, I've learned things while reviewing the course. Estelle Weyl did a great job of digging into all of the details of the HTML spec, and whether you are new to web development, or an old-timer like me, I'm pretty sure you'll find something new there.

The API that drives this is currently experimental in Chrome, however this demo helps to demonstrate what the Scroll-driven animations spec can do.
