CSS Layout News - 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.

Interesting post about using CSS to crop images, while respecting their focal point. Also, I love the layout of this site. The left-aligned headings on a wide screen work really well.
