creating a qr code

👾Hi @alinco6426, congratulations on your solution!👋 Welcome to the Frontend Mentor Coding Community!

Great solution and a great start! From what I saw you’re on the right track. I’ve few suggestions for you that you can consider adding to your code:

• Instead of using h3 for the heading, it's better you use <h1> since this is the main heading for this page. Remember that any page needs a h1 heading to display which is the more important text. Note that you need to increase the headings by one level, like h1, h2, h3 to show the titles hierarchy and you cannot have more than one h1 heading.
• Use <main> instead of a simple <div> this way you improve the semantics and accessibility showing which is the main block of content on this page. Remember that every page should have a <main> block and that <div> doesn't have any semantic meaning.
• Add a margin of around margin: 20px to avoid the card touching the screen edges while it scales down.
• Use relative units as rem or em instead of px to improve your performance by resizing fonts between different screens and devices. These units are better to make your website more accessible. REM does not just apply to font size, but to all sizes as well.
