Yes, but that's special-casing the colour things.  :-)  If you have

<p style="border: 3px;">foo<p>bar

then only the top-level p should have a border, and the next one
shouldn't.  But it's kinda moot, since I don't think any of the
properties we're interested in have this kinda of behaviour.

Yes...  except that we're setting the colour after rendering all the
children today.  So I think we'll have to have the inheritance as well
as the non-overwriting colour property stuff to get it right.

I'm not sure how selectors like

p.foo > div > p { colour: red; }

selectors fit in here.  I suspect it doesn't.  :-)

I'll take a whack at implementing the inheritance thing, and we'll see
how that goes...
