Answer 5

The first one selects all elements with .closs which have an ancestor of an element with .class.
The second one selects all .class AND .closs elements.

Also...
.class > .closs will select all .closs that have a direct parent which is a .class.
.class + .closs selects all .closs that come after a .class element, and they both have the same parent. You can use this to make a dropdown, such as this simple code here:
