h5Validate Needs a Refresh

[ericelliott]

Implement missing features as described here:

Add support for email type, at minimum (very handy for mobile).

Take a fresh look at new input types (Specifically, can we disable the horrible default browser UI for number types? Can we make it easy for users to override built-in browser date pickers, etc...?) Sadly, the spec leaves a lot of those implementation decisions to the browser, without specifying standard ways to override them or style them, but we might be able to track down all the browser implementations.

I'm open to help with these things. I'm not sure when I'll find time.
