Learned on today’s CSSWG call—I had a fundamentally out-of-date mental model of how the display property structures its values.

It’s not display: <value>;. It’s display: <outer-value> <inner-value>;.

This realization won’t change what I write in my code, but it does change how I think about what I’m writing.

display: grid; = display: block grid;
display: flex; = display: block flex;

Also: display: inline grid;

You can write display: inline-grid;, but that’s actually out of date. It makes more sense to write display: inline grid;

I find myself with IoT talking about progressive enhancement all the time, even though it’s a Web thing, but it makes even more sense. Really, it should be the thing it was designed to be first and then the smarts layered on top.

Stephanie Rieger on a recent episode of The Web Ahead podcast, speaking with Jen Simmons about designing network-connected physical devices—ahem the Internet of Things—with the philosophy of progressive enhancement baked in. Sure, you could build a Web-connected light switch, but if it isn’t first a well-designed light switch, you’ve missed the mark.
