I'm in San Francisco today at Smashing Conf, teaching people CSS Layout yesterday in an all-day workshop. I'm not speaking at the conference so this is chance to hang out with the Smashing team and a bunch of other fine folk in the sunshine here in SF. If you are at the conference come and say hi!
At my workshop yesterday I was able to show attendees some of the upcoming CSS Grid subgrid functionality. I've also written that up on my blog and it is linked below, I'm so excited to see this on the way!
