When we select id "wrapper" in main.css, we type: wrapper{} However, when we select class "selected", why do we have to type nav a.selected{}? why can't we just type .selected{} directly like we did with wrapper? Thanks for your reply!

you know you are selecting only one element, but if you write .selected
you could be selecting multiple elements because that class may be applied to more than the just the anchor in the nav. So it's just a little safer to be more specific and write nav a.selected
. It's perfectly valid to write .selected
, but in this case I guess they want to be more specific.

Example
main.css:
.selected{color:blue;} nav a.selected{color:red;}
index.html:
<nav class="selected"> <a>Home</a> <a class="selected">Contact</a> </nav>
In this example you can see the class selected in the nav tag and the a tag, but "Home" is blue and "Contact" is red.
I hope I explained well!
