  Replace<div class="card-qr">with the main tag, <h2> with <h1> and <div class="attribution"> with the footer tag to fix the accessibility issues. click here for more on web-accessibility and semantic html

  Give the alt attribute in the img a value. The value of the alt attribute is the description of the image. For decorative images like icons, there is no need to give it an alt value, for more on alt attribute Click here.

  Give h1 and p the same font-size of 15px which is 0.9375rem, text-align: center,the same margin-left, margin-right and margin-top values. Give p a margin bottom value.

  For a responsive content,

  • Replace the width in .card-qr with a fixed max-width value and give it a padding a padding value for all the sides max-width:320px which is 20rem padding:16px which is 1rem/em
  • Give the img a max-width of 100% and a border-radius value, the rest are not needed.

  To center .card-qr on the page using flexbox or grid instead of position: absolute and margin,

  • 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

  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.

  ---

  HTML 🏷️:

  • This solution generates accessibility error reports, "All page content should be contained by landmarks" is due to non-semantic markup, which causes lacking of landmark for a webpage

  ---

  • So fix it by replacing the <div class="card-qr"> element with the semantic element <main> along with <div class="attribution"> into a <footer> element in your index.html file to improve accessibility and organization of your page.

  ---

  • What is meant by landmark ?, They used to define major sections of your page instead of relying on generic elements like <div> or <span>

  ---

  • They convey the structure of your page. For example, the <main> element should include all content directly related to the page's main idea, so there should only be one per page

  ---

  HEADINGS ⚠️:

  ---

  • And, this solution has also generated accessibility error report due to lack of level-one heading <h1>

  ---

  • Every site must want at least one h1 element identifying and describing the main content of the page.

  ---

  • An h1 heading provides an important navigation point for users of assistive technologies, allowing them to easily find the main content of the page.

  ---

  • So we want to add a level-one heading to improve accessibility by reading aloud the heading by screen readers, you can achieve this by adding a sr-only class to hide it from visual users (it will be useful for visually impaired users)

  ---

  CSS 🎨:

  • let me explain, How you can easily center the component.

  ---

  • We don't need to use margin and padding to center the component both horizontally & vertically. Because using margin or padding 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

  .card {
      margin: auto;
  }
  

  ---

  .

  I hope you find this helpful 😄 Above all, the solution you submitted is great !

  Happy coding!
