Result Summary Component

Great solution. There's not much to improve on, but if we're going to nitpick:

• The "summary" header is in line with the list if you look at the design. Simply adjust your margin on your li to margin: 8px 10px 18px 0px; to get them in line.
• Avoid using percentages for your border radius, otherwise you get a weird pointy/curvy corner.
• Increase the border-radius on the button for a more pill shape look.
• Implement the mobile design.

Hope this helps. Happy coding :)
