I'm briefly back in the UK before heading to Orlando for An Event Apart. Last Saturday I presented a talk on modern layout methods demonstrating various things about Flexbox, Grid and Box Alignment over in Prague for WebExpo. You can find my slides and all the code here I believe a video of that talk will be posted soon.
The CSS Grid Layout specification is set to become a Candidate Recommendation this week, which is a big step towards us having it available in production. It's likely that early next year it will start emerging from behind a flag in browsers - exciting times!
On the 10th of October I'm doing an AMA over at Hashnode. To be fair you can pretty much ask me anything anyway, I generally do reply to emails. However if you want to ask me anything in a public forum - there is your chance!
-webkit prefix was removed from Grid Layout in Webkit, a runtime flag was added however this was enabled by default in Webkit Nightlies and Safari Technology Preview. At some point the default has been changed in Safari Technology Preview and now to enable Grid Layout you need to use the Develop Menu, and the flag is under Experimental Features.
For the latest in browser information for Grid, keep an eye on my Browsers page.
