CSS grid

[o-t-w]

Technically display: grid is supported in certain browsers (Gmail web client, Outlook web client). You can look at devtools and see that it hasn't been stripped out, but it's pretty pointless by itself. The properties that go with it grid-template-columns etc aren't generally supported. I wonder what the best way to convey that is? We should probably add separate pages for the different grid properties.
I wasn't able to replicated the supports value for Gmail mobile webmail. Maybe that was reported innacurately? It's not a great client in general so I was surprised to see it as green.
The test for CSS grid support seems a bit random. I can't tell how its meant to work from looking at the css-display.html test file.

I think css-display.html was made to test inline, block and inline-block values but not really grid. The test used in the grid page is css-box-model.html (https://www.caniemail.com/tests/css-box-model.html), which is one of the earliest test we had and is a bit all over the place.

So please feel free to make a new test dedicated to grid (or a test file for each individual grid properties)!
