CSS on GitHub Pages not Updating

I am doing a SkillShare course that uses GitHub pages to host HTML web pages. I uploaded an early version of the CSS stylesheet, which displayed just fine on GitHub Pages. However, when I uploaded the final version, GitHub Pages won’t update the CSS style. It doesn’t matter what browser I use, what device I use, or anything. The stylesheet refuses to update, but it works without any flaws when running locally on my machine.

Here is a code snippet of how I implemented the code:

Here is a link to both the page and my repository:

UPDATE: I managed to fix the issue by making comments in my CSS file. not sure why that fixed the issue but it did.
