Mobile-first Order Summary Component Using HTML, Scss, Flexbox

I finished this project today and I tried to correct certain mistakes I made on my last solution regarding accessibility. I had to do the #nomouse challenge working around the Order Summary with just the keyboard. I also added label elements with screen-reader users in mind. I'm trying to fine tune my consciousness on writing code that is accessible to different users. Please feel free to run through my code. I'm open to receiving positive feedback. Thanks!
