Feature Queries in CSS using
@supports are like having Modernizr right there in CSS. Here is an article from Jen Simmons explaining how to use them.
Navigation is hard. I'm thinking that quite a lot recently as the various things I'm involved with seem to all have their own special navigational headaches! Here is an excellent post with lots of examples of breadcrumb navigation.
Justin McDowell shows some demos of Viewport Units, Transforms, Grid and Shapes in this presentation from CascadiaJS. Watching this I think I solved my question as to why lots of people were telling me that CSS Grid Layout was going to be in Safari 10.
As far as I know that isn't the case (not that I have special knowledge). I think this misconception comes from Grid being enabled in Safari Technology Preview. My understanding is that the things in Preview are like the things in Chrome Canary, they aren't going to ship wholesale into any particular version but are just there for testing.
Anyhow, I like to see people taking a creative look at the possibilities with new layout methods, which Justin does nicely.
And another video from CascadiaJS in which co-chair of the CSS Working Group, Alan Stearns, talks about something I care about a lot.
"How people can engage in standards discussions, log bugs and write testcases, and how the Houdini task force will let more people write better code for styling."
An excerpt from Chris Coyier's new book, Practical SVG. The book is excellent and worth buying but this excerpt is especially relevant to this newsletter as it covers sizing SVG elements.
A solid introduction to Flexbox on the Mozilla Developer Network Learn section.
