Pseudo-elements in the Web Animations API

14.5.2020
To use the Web Animations API (e.g. el.animate()) you need a reference to a DOM element to target. So, how do you use it on pseudo-elements, which don’t really offer a direct reference? Dan Wilson covers a (newish?) part of the API itself: const logo...

React Single File Components Are Here

13.5.2020
Shawn Wang is talking about RedwoodJS here: …  it is the first time React components are being expressed in a single file format with explicit conventions. Which is the RedwoodJS idea of Cells. To me, it feels like a slightly cleaner version of how Apollo wants you to do it with useQuery....

9.5.2020
I mentioned this the other day via Michelle Barker’s coverage, but here I’ll link to the official announcement. The main thing is that we’ll be getting gap with flexbox, which means: .flex-parent { display: flex; gap: 1rem; } .flex-child { flex: 1; } That’s excellent...
