Some css not working

Hi, I've managed to get the site up and running. I have multiple style sheets. The static directories have been set up correctly. The problem is... I have a style that sets the height to 100vh and overflow to scroll. It doesn't work. All other css from that file is working fine. when I run on my local server, it works fine. If I use Chrome inspector, and change it; it works. As soon as I click back to the page, it stops working again? very puzzling, can you help? Thanks

can you give us more details about what / how it doesn't work?

secondly, can you double check that after reloading your webapp, and clearing your browser's local cache, you are still seeing this problem?
