QR Code Challenge using HTML 5 and CSS

Hi, @superuser2345!

I have a few suggestions for you:

• Your page should contain landmarks, so it makes your code easier to read on what content is what and also helps screen-readers to figure out what is what. In this case your card should be wrapped withing main tags and your attribution should be wrapped within footer tags.
• You are writing your CSS within the HTML, I would suggest making a separate file for CSS. Imagine this was a big website with a lot of styling and markup.
• You have separate index files for desktop and mobile, your page should be one file and responsive based on the screen width. I would suggest looking up "Media Queries". Currently your page is not looking good on a mobile screen. Use browser inspect tools to test different screen widths and responsiveness.
• Centering elements using margins is considered bad practice, I would suggest looking up "Flexbox" as an approach to aligning elements.
• Try to avoid using px values as much as possible and use rem instead.
• Try to start using "custom CSS properties". While this is not essential in this project, it is a good habit to develop.
• I would also suggest using a CSS reset.

Hope this helps!
