  Hello, @rozinsrjr262!

  Your project is looking fantastic!

  I'd like to suggest a way to make it even better:

  • Although it works, using position isn't always the most effective method for centering an element. It can cause bugs as well as result in part of the content being cut off on smaller screens depending on the length of the card.

  Here's a highly efficient approach to position an element at the center of the page both vertically and horizontally:

  📌 Apply this CSS to the body (avoid using position or margins in order to work correctly):

  body {
      min-height: 100vh;
      display: flex; 
      justify-content: center;
      align-items: center;
  }
  

  I hope you find this helpful!

  Keep up the excellent work!

  HTML:

  • Every webpage needs a <main> that wraps all of the content, except for <header> and footer>. This is vital for accessibility, as it helps screen readers identify a page's "main" section. Wrap the card in a <main>.

  • The image has meaning, so it must have proper alt text. Write something short and descriptive, without including words like "image" or "photo". Screen readers start announcing images with "image", so an alt text of "image of qr code" would be read like this: "image, image of qr code". The alt text must also say where it leads(frontendmentor website).

  CSS:

  • Including a CSS Reset at the top is good practice.

  • Add around 1rem of padding on the body, so the card doesn't touch the edges on small screens.

  • Remove the html selector.

  • Remove the height on body.

  • Remove the margin on the card.

  • To center the card horizontally and vertically, use Flexbox on the body:

  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  min-height: 100svh;
  

  • Remove ALL widths and heights in px. Setting fixed sizes is not recommended, as it prevents the elements from being responsive.

  • Add a max-width of around 20rem on the card, to prevent it from getting too wide on larger screens.

  • Remove the positioning and transform properties.

  • font-size must never be in px. This is a big accessibility issue, as it prevents the font size from scaling with the user's default setting in the browser. Use rem instead.

  • Since all of the text should be centered, you only need to set text-align: center on the body, and remove it elsewhere. The children will inherit the value.

  • Paragraphs have a default value of font-weight: 400, so there is no need to declare it.

  • On the image, add display: block and max-width: 100% - the max-width prevents it from overflowing its container. Remove the margin.

  • To create the space between the image and the edge of the card, set padding on all 4 sides of the card:padding: 16px;.
