Four card feature section 🌜 Dark-mode / Light-mode feature

Hello my fellow developers ! Here is my solution for this challenge with a extra feature :

• I used grid to position cards.
• I added dark and light mode as a extra feature.

And I have some questions :

• It's first time I'm adding dark-mode to my project and I was very unfamiliar and had to do a lot of research, What are best practices to create dark mode using sass ? Is my approach any good ?

• This should've loaded initial theme based on user's OS theme, But it seems like It's not working after deployment, does it work for you?

• Can you switch themes or is my solution broken ? 😐
