CSS Grid lands in Firefox 52 - the Firefox web browser, made by the Mozilla Foundation, is the first major browser to provide full support for the CSS Grid Layout module. This should become the defacto layout technique for most of our work going forward. Exciting times!
In The Future of Loading CSS, Jake Archibald takes a look at how best to load CSS. Up to now, as CSS normally blocks page rendering, we've usually combined all styles into one file and loaded them after the main content has been downloaded. However, an update to the Chrome browser, bringing it into line with Microsoft's Edge browser, could help to change CSS loading best practise. The general idea is that we load multiple smaller CSS files that in turn render the content that directly follows it, resulting in a more progessive page render.
