Basis: Update box-sizing method

[ghost]

Basis has the following in its base.css file:

* {
  box-sizing: border-box;
}

According to CSS-Tricks, this is an old method of setting box-sizing. There's an updated method that may be better:

html {
  box-sizing: border-box;
}
*, *:before, *:after {
  box-sizing: inherit;
}

This newer method not only helps with pseudo elements, but also allows easier overriding of box-sizing if need be (see the linked article for more details).

Can/should we update Basis to use the newer method?

I suspect that someone should just write a Pull Request for this change and see what happens.
:-)
I don't see a reason NOT to make this change.....
Also, not seeing any urgency to it.

Would this have any affect on existing sites?

@jenlampton Existing sites (that use Basis) would be affected, but as to whether or not they'd notice any visible difference...? I don't know.
