Blog card preview using CSS Flex box

Hey, Great job with this solution you should be proud, A few things I noticed,

• Missing a <meta> description tag for SEO purposes,
• ‍Using max-width: 100% or min-width: 100% is way more responsive then just width:100%, check out this article also from the same Frontend mentor dev responsive-meaning, she goes into more detail.
• You should apply a full modern reset to make things easier as you build, check out this site for a Full modern reset
• Using a naming convention like BEM, Using proper naming will prepare you for the changes in design of the website.

Hard for me to give any feedback, I hope you found some of this information helpful, Great solution and you should be proud, Hope you have a good day, Happy Coding!
