Great write up and lets hope that we finally see editorial design being used at page level rather than site level now. With the addition of http/2 and these techniques, editorial design is now more possible than ever. Love the examples you have used!

Thanks for this, its easy to let the world – and new web design techniques – pass by so I really appreciate a good primer on new and old topics.

A very cool feature, underappreciated and largely misunderstood – thank you for this great article! You explained everything really well. Makes me want to try working with @supports on my next project.
