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)
This is because your css file is not properly connected to the html file.
In your index.html file, You have did something like this:
<link rel="stylesheet" href="{{url_for('static',filename='../static/styles.css')}}">
Well, it's a wrong format to do so. You must do it like this:
<link rel="stylesheet" href="{{url_for('static',filename='/styles.css')}}">
You don't need to write the ../static/ path because it's already done in url_for('static'. I hope you understood
