Blog-preview-card using CSS Flexbox

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

I have learned about Flexbox in more details, Flexbox's different properties. I have used Google fonts in the challenge. I learned about CSS hover state and box-shadow properties. These are the things I'm most proud of. In my next challenge I would use Flexbox(if there is need) without going though the reference guide. I would also use more CSS properties (which I learned from this challenge) without going through the reference material.

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

I had issue in difference between preview pane and browser viewing of the challenge, which I had helped from discord community and they helped me to resolve my issue.

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

How can I use media-queries in my project to make it responsive. Please help me on Media-queries. I want to know more about em and rem, how they are different from px, when and where to use them. How do I decide when to use em and when to use rem?
