 This rule uses [stylehacks](https://github.com/ben-eb/stylehacks) to detect the hacks. Then, in the spirit of stylelint, it tells you that you've done something wrong.

-A [compound selector](https://www.w3.org/TR/selectors4/#compound) is a chain of one or more simple (tag, class, id, universal, attribute) selectors. If there is more than one compound selector in a complete selector, they will be separated by combinators (e.g. ` `, `+`, `>`). One reason why you might want to limit the number of compound selectors is described in the [SMACSS book](http://smacss.com/book/applicability).
