aspect-ratio not working

[EmpireJones]

I'm not 100% sure that this syntax is valid, but some tool I'm using is converting "aspect-ratio: 3000 / 3000;" to "aspect-ratio:3e3/3e3".

This results in the errors:

• "aspect-ratio": Unknown dimension.
• "aspect-ratio": "/" is not a "aspect-ratio" value.

According to https://developer.mozilla.org/en-US/docs/Web/CSS/number, scientific notation should be valid for CSS numbers.

It looks like this functionality is pretty broken in general;

As mentioned in the following comment, even things like "aspect-ratio:1;" and "aspect-ratio:1.5;" don't validate properly.

The second part (aspect-ratio with one number only) has been fixed by ad4b711. The number parsing needs to be addressed.
