@name           Darker Udemy course backgrounds
@namespace      github.com/openstyles/stylus
@version        1.0.0
@description    Quick style, just makes some of the backgrounds around Udemy videos darker. Might make some text less readable. Also has some effect on the course catalog pages for unpurchased courses, but should still be readable.
