We need some CSS guidelines for AMP about dotcom-rendering HOT 2 CLOSED

I agree, it seems sensible to at least make explicit in our docs this minimal set of rules.

We haven't yet defined a browser support strategy, but I think it should be more explicit than the one in frontend. We have previously said we'd provide a good user experience for any browser from which we receive at least 0.2% of page views. This is probably a bigger conversation, but I don't think we should consider whether we go all-in with Grid until we have more clarity around which browsers we support.

Further to your investigation, according to Google Analytics:

• 0.51% of our page views come from Opera Mini
• 3.52% of our page views come from iOS Safari <= 10.2

However, I have no problem with saying Flex has enough support for us to not even think twice about using it.

Closing as mega old, we can bring it back to life if it comes up again.
