Tomorrow I head to Athens, Greece for Frontend United. I am speaking and also running a CSS layout workshop.
I love the Firefox Grid Inspector, but I'd love to see Grid support in Chrome DevTools. There is an issue raised to add it. If you would like to see it happen, then starring the issue shows that there is interest in this as a feature.
A fairly major update to Grid by Example. I've created a Getting Started guide with links to various things I have written and recorded, on and off the site.
Also the beginnings of a whole new section of patterns which include fallbacks for older browsers.
People keep asking me about animating the grid. Happy to see a post explaining what is animatable and demonstrating the fact that there is poor browser support currently.
