https://drafts.csswg.org/selectors-4/#specificity says this:

> A selector’s specificity is calculated for a given element as follows:
> 
> - count the number of ID selectors in the selector (= A)
> - count the number of class selectors, attributes selectors, and pseudo-classes in the selector (= B)
> - **count the number of type selectors and pseudo-elements in the selector (= C)**
> - ignore the universal selector
