Responsiveness using flexbox

Hi there! I looked through your code and if you don’t mind I will provide some feedback :).

So first of all it is good to separate our styles and html, for small projects it is acceptable to write our css inside html but we usually write it in a separate file and then connect it via link tak inside the head element.

It appears that you don’t use <h1> element which is necessary to include even in small projects, we want to use heading hierarchy which starts with<h1> and moves to <h6>, it improves readability of our code and helps screen readers to understand content of our page better. Here is some good resource on that:

Hope it was helpful for you at least a little bit ;)

Good luck on next projects and happy coding!
