Grid css resources to read/dissect/post examples for use

• Flexbox and Grids, your layout’s best friends
• CSS Grid for Designers – Times Open
• Making Future Interfaces: Algorithmic Layouts - YouTube

I'd like to create examples that fall back to flexbox and then floats.

This is why I don't like grid, at first glance, as it requires a bit of "falling back" to do; most clients I work with need at least IE11 support (and if you're doing that, IE10 is just a stone's throw away).
