Sam Atkins 2dad3dca9a Base: Add ratio tests to media-query test page
Note that only the first test actually functions currently.
Single-number ratios instead get parsed as a `<number>`, and will do
until the parser gets smarter. (The alternative, where all
single-numbers get parsed as `<ratio>`, does make the tests succeed,
but numbers are more common than ratios so I have given numbers
preference for now.)

Also simplified the styling and text a bit. Now, red = fail, green =
success. No more "unstyled = fail" stuff.
