Order Summary Component using Flexbox

Hi, I prefer using rem units because the math is a lot simpler. If you set your root HTML font size to 62.5% which is 10px. The body font size would calculate to be 16/10 = 1.6rem. You did a great job and I suggest you can add a min-height 100vh rather than height 100vh because the element would occupy space of the web page. Here is an article explaining min-height: https://www.positioniseverything.net/css-min-height/ Hope this helps.
