Blog Preview Card Main

I'm back after ten months of not being active, and I realized a person can forget a lot when not doing something, so decided to start from the very beginning.

This is my solution for the Blog preview card

As always all comments are welcome because I am trying to pick up everything I've forgotten and also learn something new.

I have one question though: At the challenge page there was "ideas to test yourself" box and one of the ideas was to change the font size on mobile without media queries. Can someone explain how to do that?

Thank you in advance for everything you do to help me
