Social Links Profile using CSS Flexbox

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

Being able to understand how Flexbox works and understand how to group and organize elements in a container. I was also able to use media-queries better this time(I'm a newbie to html and css).

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

Not being able to place the container in the middle of the page with place-content: center together with flex. I understood I have to set the flex-wrap: wrap. For some reason, when you want to align the content in the middle using align-content property, you also have to set the flex-wrap. I saw that you could avoid this using align-items: center

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

How do I set the most appropriate distances between elements? Are there any useful free tools for that?
