Order Summary Component with HTML CSS and Flex

Heya, great job on this one! Looks pretty close to the original design, just a few small improvements needed:

1. Setting a background-size: contain on the body would make the background image look a bit nicer instead of being cut off ^^

2. Alt text for the hero image: " Background Illustration" isn't the best choice. If you think this image is only decorative, you can leave its alt text empty. If not, then you should help people who can't see the image (people using screen readers or have images turned off in the browser) to have an idea what the picture is about. Something like "Girl listening to music." or whatever you feel appropriate.

3. I'd say using classes instead of IDs would be a good idea. Although this is a small project only, in real life your aim is to create reusable elements and styles and IDs are not suitable for that.

4. Avoid inline styling at all costs, you have a stylesheet linked to your html for styling purposes.

5. Headings: headings have a semantic meaning and should not be used for styling (their looks you can change with css anyway), so you should always start from <h1> going down by one every time you need a heading.

6. Your main div could be swapped for main, your attribution div to footer to make things more semantic.

It was a great idea to add a custom README to your project though, it's very nice to see your thought process! On that note, I don't think you should change the payment button to a link. :) Button is the most appropriate element here. If you want the cursor to show, you can add cursor: pointer to pretty much any element, even to a div (this doesn't make the div clickable). Not sure why you'd do that though :D
