Point one style class to another?

Question

I have a css class like:

.foo {
  background-color: red;
}

then I have a class specified for a list:

.list1 li {
  background-c         


        

Answer 1

Not with any syntax like that (and don't confuse a "class" (an HTML term) with a "class selector" or a "rule-set").

Your options are multiple classes, grouping selectors or preprocessing.
