Flexbox summary component

Congrats on completing the challenge, @ArthurWilliams!

Your solution looks really good, both on desktop and mobile screen sizes. Just a few suggestions based on your final solution and Github code:

• Make the card a bit smaller on desktop screen sizes - consider adding some padding around it

• Fix the positioning of the background image on mobile screen size

• Use more classes in your HTML code - there are still quite a few HTML elements that don't have any classes set on them

• Consider storing your SCSS variables in a separate file

• You don't need to set height: 100% on html, body, main. You can simply use min-height: 100vh
