I have a website hosted on an EC2 server with Flask and uwsgi, and I run it with docker. The problem is that the CSS file that I see in DevTools is empty(css file empty in the website, but the file has code when i check it on my computer), but when I open the CSS file on my computer, the file has code in it. I've uploaded the code to GitHub here. I can insert CSS code(copy and paste) into the empty file I see in DevTools and it updates the website, so I don't think it can be the linking.
EDIT: I changed the code to proper formatting for the url_for, it didnt help, the static folder is still empty(i see the images, js, css in my editor but not with devtools and it doesnt show on my website)
