What should be improved?

Some percentage values can be re-written as unitless factors, notably in CSS transforms:
E.g. .test { transform: scale(-100%); } can be also written as .test { transform: scale(-1); }.

Describe the solution you would like

Reduce percentage values to unitless values, where possible.

Possible alternatives

Do not rewrite those percentage values, but leave this kind of minification on the table.

Additional context

The computed styles for transforms for example are matrices containing elements with unitless values anyway.
E.g. reducing 100% to 1 for example shaves off 3 bytes, this depends on the value of course,
as 1.45% could be rewritten as 0.145, which does not save bytes (but – it may compress better with gzip).

Are you willing to work on this?
