Blog preview card with CSS and HTML

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

This was fun and it felt pretty fast.

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

I'm unsure how to name the different font sizes.

I left p/16px/1rem as the body text. I used h2 for the card title on purpose, thinking the h1 would be on top of the page.

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

Should I handle the rest (the tag/chip with Learning, the date and the name) as h3 and h4, or as different p classes? I'm sure it depends on the project, but is there best practices on how to approach it if it's a small component, like this card?
