Order summary responsive with media queries and calc() for width

Hi VincenzoMuolo, how are you?

I really liked the result of your project, but I have some tips that I think you will enjoy:

If we see how the layout is behaving at higher resolutions, with the help of google dev tools, we will see that it is stretching a lot, to solve this we can use a max-width with the value we want the content to stop growing and to center use a margin: 0 auto;

example:

@media screen and (min-width: 1440px)
main {
    max-width: 500px;
}

The rest is great!

I hope it helps... 👍
