  Hello 👋. Congratulation on successfully completing your first challenge 🎉 ! !

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

  HTML 📄:

  • Use semantic elements such as <main> and <footer> to improve accessibility and organization of your page.

  • 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. You can read more about this here 📘.

  • The width: 100% property in the body tag is not necessary. The body tag is a block element and it will take the full width of the page by default.

  • The simplest way to set the height of the .wrapper element is with min-height: 100vh, setting the height to 100% on the body and html elements can cause your component to be cut off on small screens, such as a mobile phone in landscape mode. screenshot-imgur (taking into account the scroll) 📸

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

  Happy coding!

  Hey whats up!

  I have a few suggestions for you to improve your code:

  • Dont use<div>for everything. There are many other tags whitch you can use for better accessibility.

  For example insted of this:

  <div class="card"></div>
  

  Use this:

  <main class="card"></main>
  

  Whatch this video about correct use HTML semantics.

  • I also suggest to start using rem units instead of px:

  here are a video about units.

  • Always use alt attribute on <img> to specify an alternate text for an image, if the image cannot be displayed.

  Happy coding! :)

  Replace<div class="wrapper">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

  Add the alt attribute alt=" " to the img tag to fix the error issue. The value of the alt attribute is the description of the image.

  There is no need to give the body a width and height value To center .wrapper on the page using flexbox, add min-height:100vh, display: flex, align-items: center, justify-content: center to the body.

  To center .container on the page using flexbox:
  body{
  min-height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
  }
  

  There is no need to give .wrapper a margin value. Reduce the max-width value of .wrapper and the padding value of .container for it to be equivalent to the width and padding of the design. max-width: 320px; padding: 15px.

  Give the img a max-width of 100% and a border-radius value. the rest is not needed.

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

  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
