My understanding is that using element.class should allow for a specific element assigned to a class to receive different \"styling\" than the rest of the class
element.class
h2.myClass is only valid for h2 elements which got the class myClass directly assigned.
h2.myClass
h2
myClass
Your want to note it like this:
.myClass h2
Which selects all children of myClass which have the tagname h2
