Why Do CSS and JS Files Fail to Load in My Django App?

MIME Type Configuration Issue with CSS and JS in Django

In Django applications running within a virtual environment, users have encountered an issue where CSS and JS files fail to load, displaying an error message related to an incorrect MIME type. Specifically, the browser interprets these resources as stylesheets despite receiving them with the MIME type application/x-css.

This problem can often be resolved by ensuring the correct MIME type configuration for CSS files in Django. One approach is to modify the settings.py file to include the following code:

import mimetypes
mimetypes.add_type("text/css", ".css", True)

This code adds the MIME type for CSS files to the application's configuration, ensuring the browser properly renders these resources. It is important to note that adding this code may not be necessary in all cases, depending on the specific Django configuration and server setup.

If the issue persists after modifying the MIME type configuration, it is recommended to check the following:

• Verify that the CSS and JS files are located in the correct static file directory.
• Check the web server configuration to ensure it is set up to serve static files correctly.
• Examine the browser's network tab for any additional error messages or indications of network requests failing.
