Mobile-first using CSS flexbox

Hi there! I'm currently doing a full-stack intensive course and these challenges are very helpful in refining my CSS skills.

What did you find difficult while building the project? I didn't quite manage to center the list markers for the unordered lists, to vertically align it with the text. This seems overtly complicated (using flexbox within each <li> item) for such a small effect. Is there a better way to do this?

Do you have any questions about best practices? I'm learning a lot through these challenges, but I'm sure there are many, many areas for improvement. Things I don't see/know I'm missing. If you spot obvious areas for improvement, please let me know. I'm excited about improving my skills.

Many thanks!
