Responsive Bento Grid Design using HTML and Vanilla CSS

What are you most proud of, and what would you do differently next time?

Proudly completed this challenge.

What challenges did you encounter, and how did you overcome them?

Nothing special

What specific areas of your project would you like help with?

The special areas I would like to improve are semantic HTML, accessibility, BEM, and making the code reusable, readable, and clean.

If anyone could help me to improve my code that would be helpful and appreciated.
