QR Code Component

I encourage you to use this technique to make the card responsive with ease:

.card {
width: 90%;
max-width: 37.5rem;
}

On the smaller screens card will be 90% of the parent (here body), but as soon as the card will be 37.5rem (600px) it will lock with this size.

Also to put the card in the center I advise you to use this code snippet:

.container {
display: grid;
place-items: center;
}

Good job and keep going 😁😊😉

Hey, Great job with this solution you should be proud, A few things I noticed,

• Missing a <meta> description tag for SEO purposes,
• Setting a height and width attribute to your <img> will increase performance to reduce layout shifts and improve CLS, It reserves the space on the page for the image,
• It is best practice to have a <main> tag inside your body highlighting the main section.
• ‍Using max-width: 100% or min-width: 100% is way more responsive then just width:100%, check out this article also from the same Frontend mentor dev responsive-meaning, she goes into more detail.
• You should avoid using px as it is an absolute unit and not a responsive unit like rem or em, You should look at this article from a Frontend mentor dev, Why font-size must NEVER be in pixels.
• Another great resource for px to rem converter.
• Having better alt="" descriptions for accessibility is a must check this out Write helpful Alt Text to describe images,
• You should apply a full modern reset to make things easier as you build, check out this site for a Full modern reset
• Using a naming convention like BEM, Using proper naming will prepare you for the changes in design of the website.
• @media should also be in relative units like rem or em,
• It is best practice to use margin-inline: auto; to center left and right then than just margin: auto;, You can center the height by using this code snippet

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