Hey! Welcome and glad you have already figured out almost all the tests.
To make that one test pass you have to keep in mind that you can use CSS to make any element (including your section) to be the same height as the viewport.
Just like how we have sizing units for px, rem and em in CSS; there is a sizing unit called vw for the width of the viewport and vh for the height. For example if you set a heigh of an element to 10vh, CSS would resize that element’s height to be 10% of viewport.
I hope this is enough of a hint but if it wasn’t make a comment below and we should be able to figure it out!
