Re: #id.class or #id .class

Take a look at this and I think you’ll understand:

body#page-home #topnav ul li a.tn-home

What that’s basically saying is, “body with id of page-home which is a parent of element with id of topnav which is a parent of a ul which is a parent of an li which is a parent of a with a class of tn-home.”
