Courses Plus Student 44,108 PointsBecause the element is positioned as fixed
and as such needs to be positioned in relation to the view port. Setting the top offset to 0
fixes it to the top of the page.
Try experimenting a bit, set a bottom offset to 0
instead and see what happens. Or set it to some other number. The best way to understand how properties in CSS relate to each other is to experiment with them.
