The instructions say to "select all links inside the <nav> element", but this code doesn't select any links. Links are implemented using anchor (a) elements (and "li" is for "list item"s).

Also, you don't need to be so specific in the selector. It's enough just to name the outer container and the target elements with a descendant relationship (space). So "nav a" will do the trick.
