Nifty little site! Though I don't think it's a great 'learning' tool. I would love if it presented multiple ways of achieving the same layout (EG legacy, flex, grid), so you could compare and see which is best. For example, the 'holy grail' layout used to be done using tables. Then we moved away from tables, to using divs with clearfix and other positioning hacks. I lean heavily on flex these days - but they only show grid. I think it would be interesting to see the reason why grid was picked, by comparing it to other methods - so you can show off how clean the implementation is by contrast.
