I’ve seen the following two notations on CSS pages, and they seem to work the same, is there a difference between them?
.ClassName a:hover
And:
a.ClassName:hover
Yes, there is a difference between them.
.ClassName a:hoverrefers to any hovered anchor that is within an element withclass="ClassName".a.ClassName:hover, however, refers to any hovered anchor that hasclass="ClassName".There is lots of information regarding CSS Selectors at W3.org.
