build blog-preview-card using HTML and CSS

Awesome. You used flexbox correctly and on point.

I have a few simple suggestions:

1. In your .tag selector, instead of using width: 75px; you can use something like width: fit-content; or width: min-content; to make the width just as much as the content inside it.

2. In your .person you used flexbox which is correct but if you make the image bigger, you will notice that they are not on the same horizontal line. You can use align-items: center; to center them vertically and they will appear on the same line.

For mobile devices, you should use media queries to make it a little smaller and more suitable for those devices.
