Can all the subclasses of `CssValue` be compared with correct result?

What about different units? `font-size: 1em` shouldn't be equal to `font-size:
1ex`, should it?
What about keywords? Currently, declarations `font-size: smaller` and
`font-size: larger` are considered equal.

Could you be consistent?
The indentation at [lines
2035-2036](https://github.com/openjdk/jdk/pull/13405/files/2bc265cdb1ed0d070b21233ff9982758bef6da71..717d1a1d4e8a3eb0cea848a7e8800210f30660fd#diff-e2c9b23b1844fa877fb1c4f048a8a8b85cd21d146f963837e039ab20b9560fe7R2036)
above is different.
Personally, I would align `&&` with `v` of `val`; aligning to start of
`instanceof` look good too, I prefer it compared to 8-column indent you used
above.

Why are percentage values never equal?
I expect two attribute sets produced from `"margin-top: 100%"` to be equal.
However, the real length on rendering could be different if the attribute is
applied to different elements.

What about different units? "1mm" should not be equal to "1cm", should it?
