  Hi there 👋. Good job on completing the challenge ! I have some feedback for you if you want to improve your code.

  HTML:

  • Use the <main> tag to wrap all the main content of the page instead of the <div> tag. With this semantic element you can improve the accessibility of your page.

  • Use the <footer> tag to wrap the footer of the page instead of the <div class="attribution">. The <footer> element contains information about the author of the page, the copyright, and other legal information.

  • You must use a level-one heading (h1) even though this is not a full-page challenge. You can create an '<h1>' element within your 'main' element that will be hidden visually but visible and readable by screen readers. The class "sr-only" hides content visually and here are the styles to copy. e.g.: <h1 class="sr-only">QR Card Component</h1>

  • The <br> tag is not a semantic element. If a screen reader user is reading the page, they will hear "line break", which breaks the flow of the content. Instead, use CSS properties like margin and padding to add vertical space between elements.

  • Since this component involves scanning the QR code, the image is not a decoration, so it must have an alt attribute. The alt attribute should explain its purpose. e.g. QR code to frontendmentor.io

  CSS:

  • Instead of using pixels in font-size, use relative units like em or rem. The font-size in absolute units like pixels does not scale with the user's browser settings. This can cause accessibility issues for users who have set their browser to use a larger font size. You can read more about this here.

  • To center the component in the page, you should use Flexbox or Grid layout. You can read more about centering in CSS here. You can read more about centering in CSS here.

  • You should use a CSS reset to remove the default browser styles and make your page look the same in all browsers.

  Popular CSS resets:

  • Normalize.css
  • Reset CSS
  • Mini-reset.css

  I hope you find it useful! 😄 Above all, the solution you submitted is great!

  Happy coding and Happy New Year! 🎉🎊🎁
