Order summary component - card project using CSS Flexbox

almost looking exactly like the design, so that's very good

few improvements can be made though

HTML/accessibility

• There's no landmark being used. Yes you used a <section> however, that doesn't correspond with a landmark role.
• You have a lot of <div> wrapper elements which are (mostly) unnecessary

CSS

• there's a breakpoint for the smaller screen sizes but that one also has a minimum
• you'll be better off coding things mobile-first instead of desktop-first (which i feel you're doing now)
• a lot of px-based values, which are totally unresponsive
• you should use min-height as opposed to height so elements get room to expand when needed instead of causing issues with overflow
