Courses Plus Student 94,592 PointsHi Oliver,
There's already a class name there, for example, class="books"
If you don't put the space before "on" then the new class value would be "bookson"
Instead we want it to be "books on" with a space between. It's 2 separate class names.

echo ' on'
you can also do it like this:
<li class="books <?php if ($section == "books") {echo "on";} ?>">
Leave a blank space between books
and the opening tag of php code.
