  Replace<div class="qr-box">with the main tag to make the page accessible. click here for more on web-accessibility and semantic html

  <div class="attribution"> should be out of <div class="qr-box"> and wrap in a footer tag.

  There is no need to give the body a height and position: relative.

  For a responsive content, replace the width in .qr-box and the img with max-width.

  To center a content on a page using flexbox or grid:

  • USING FLEXBOX: add min-height:100vh; display: flex; align-items: center: justify-content: center; to the body

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

  • USING GRID: add min-height:100vh; display: grid place-items: center to the body

  body{
  min-height: 100vh;
  display: grid;
  place-items: center;
  }
  

  Use relative units like rem or em as unit for the padding, margin, width values and preferably rem for the font-size values, instead of using px which is an absolute unit. For more on CSS units Click here and here

  Hope am helpful.

  Well done for completing this challenge. HAPPY CODING

  Hello there 👋. Congratulations on successfully completing the challenge! 🎉

  • I have other recommendations regarding your code that I believe will be of great interest to you.

  ---

  CSS 🎨:

  • Let me explain, How you can easily center the component for better layout without usage of absolute positioning.

  ---

  • We don't need to use absolute to center the component both horizontally & vertically. Because using absolute will not dynamical centers our component at all states

  ---

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

  ---

  • For this demonstration we use css Grid to center the component

  body {
      min-height: 100vh;
      display: grid;
      place-items: center;
  }
  

  • Now remove these styles, after removing you can able to see the changes

  .qr-box {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
  }
  

  ---

  • Now your component has been properly centered.

  you don't need position absolute for the div, you can center it easily with grid or flex

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

  hope this helps.
