Show HN: Weekly CSS Brain Teasers by email

There are lots of small CSS problems that engage the same part of my brain that reading IQ puzzles does, including that buzz you get when you solve them.

I think there might be other devs who feel the same way, and so from next week I'll be publishing a new CSS brain teaser every Friday that I hope they'll get a kick out of. My goal is to make each challenge fun, short, and educational.
