Support more variant

[JesusTheHun]

Right now only responsive variant are supported. For text-red-900 for example, classes sm:text-red-500! are generated.
It would be great to also have other variants such as hover so hover:text-red-500! would be generated.

Hi, I believe you can add variants as you edit your Tailwind config. I'll see if I can add an example.
