I've hit an extremely frustrating wall where I am applying a custom style to a div and it won't respond. I tried refreshing the page and it simply will not work. When I completely rename the div's class it will work, but upon revisiting the page it will have reverted the class name to the class name I had before and, in turn, the styling I had before.
I cannot express how super frustrating this is. Let me know if I am missing something here: video demonstration.
