This pull request adds TypeSafe CSS: https://uglyduck.ca/typesafe-css/

This stylesheet kind of ignores form elements. I'm not sure if that meets the requirements of cssbed. But the focus of this stylesheet is reading and writing, according to the author. I think its typography makes it worthy of cssbed. But that's just one man's opinion. 😄

You can see what the form elements look like at https://deploy-preview-6--frosty-engelbart-5f4783.netlify.com/typesafe-css/

I don't really mind either way but maybe we should we wait for another vote?

Well, you know my vote. 😉
