Should have explained what echo "on" is actually doing. What does it mean? Why does echo "on" underline the nav links?

How is echo "on" underlining the anchor tags? Is it a part of css or what is actually happening?

Since we're in PHP, we are learning how to use PHP to add style. An easier way to do this IMO is to add a hover state on the elements.
