content property block

Because you can't style pseudo-content without declaring content innit.

Nice one bud! I'll add this version of the reset to a few bits I'm on over the next few weeks then get it merged if nothing terrifying happens. I'm p sure because yes, suddenly every element will have two pseudo-elements, they will be inline, so shouldn't cause issues.

I'm wondering if this can have a rendering performance impact on documents with a lot of DOM elements, at least on low end mobile devices.

Probably very small, but might be worth testing.

I am with @nhoizey I am not sure if this will have an impact on performance. If you inspect the DOM, all elements will have those pseudo elements when this is applied.
