Responsive Order Summary Component Challenge using Flexbox

With this project, I was made aware of SVG (Scalable Vector Graphics). If I only would have taken a look at my design files, I would have known that this 'curved' background, which I had so much trouble figuring out how to create, was there for me to use. I guess that's good because I used Figma to create that curve and used it in my design. It's not perfect, but it looks pretty ok. I tried minimizing my code in CSS as much as I possibly could, but it got to the point to where I didn't know what else to adjust. If anyone has any pointers, feel free to let me know! Thanks everyone...
