Isn’t ie11 incompatible with the official grid spec?

[modernerd]

Yes — I should have written IE10/11. Neither supports @supports, though, so that's still a good way to progressively enhance for grid.

[andrei_says_]

Unfortunately we’ll need to build our new site to look nice for IE11, too, as the stakeholders are locked on windows7.

That's unfortunate and likely will require a flexbox/float-based fallback.

Suzy Grids 2 is float based, a pleasure to work with and covers the old browsers. I'd love to switch to CSS grids but will have to wait another 5 years it seems.
