Blog Preview Card - HTML CSS

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

This time I had greater fluidity in recreating the design without having problems.

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

I did't have any.

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

I would like if you could review the sequence of my CSS, since I started with root elements for colors, and then from general to specific the classes of the elements. I would like to know if it is correct to write it in that order even in larger projects.
