disable dark mode in django admin

The Problem

I installed Django after couple of months. Current version is 3.2.4.

Earlier Django-admin was just light-mode. Current Django-admin switches automatically to dark or light according to system theme. Well, I do not want this behaviour. I want Django-admin to be light theme irrespective of system theme. I am Not using 3rd party theme for Django-admin.

What I Tried?

As per one of the comment in this answer,

I decided to comment "@media (prefers-color-scheme: dark)" section in /static/admin/css/base.css . Not sure that it's good solution but the fastest one.

I tried commenting the code as shown here but does not work. I tried clearing cache and even tried switching browser but none of them seems to work. In browsers, I always prefer light theme. How can I achieve this? Any help is appreciable. Thanks in advance :)

System Details:

OS: Fedora 5.11.12-300.fc34.x86_64

Python-Verion: 3.9.5

1st way: The fastest way is to go to your OS Settings and change from your theme from Dark to Light. If you are using Linux, you might need gnome-tweaks to switch between themes.

2nd way:

1. Let us consider that you are using a virtual environment named venv. Now goto the following directory venv/Lib/site-packages/django/contrib/admin/static/admin/css/base.css
2. Comment or delete all the code of prefers-color-scheme: dark. It would look something like this.

@media (prefers-color-scheme: dark) {
  :root {
      /* code */
}

3. Now if you have also executed python manage.py collectstatic and let us assume that your static folder name is static/. Comment all the code of prefers-color-scheme: dark from the following file too: /static/admin/css/base.css

Note: Sometimes browser stores the CSS files in cache memory. To hard reload all the CSS files, hard reload the admin page using Ctrl + Shift + R.
