Build a Technical Documentation Page - Story 14

Tell us what’s happening:
For this requirement:

User Story #14: On regular sized devices (laptops, desktops), the element with id="navbar" should be shown on the left side of the screen and should always be visible to the user.

My page does what it should. But the automagic test process only gives me credit for it sometimes. When the viewport covers most of the monitor, I get 16 out of 16. When the viewport is smaller, it fails.
