CSS and JS returning 404 error

[QwertyQwerty88]

It’s because it was solved in another topic.

CSS and JS returning 404 when linking in HTML (Python Flask)

Move your js and css folders into a folder called static. Then on line 10 of main.py: app = Flask(__name__, '/static') and in index.html: <link rel="stylesheet" href="../static/css/style.css"> <script src="../static/js/script.js"></script> Not sure if this will fix anything, but if it does, please mark my post as solution so the thread can close.
