Responsive using flex box

Hi Hugo. You did it very well. Even though, I'll give you some recommendations to improve your final design.

1. You should add padding to your <div class="container"> so that the elements inside don't look so tight.
2. I saw your link elements and instead of using <button type="button">GitHub</button> you should use <a href="#">GitHub</a> to make the page more accessible. This is also a good practice to use <a> tags for links.
3. Once you have improved your links. You should add some padding to make them more similar to the design.
