Responsive QR Code Component - HTML & CSS

Solution retrospective
I’m most proud of successfully building a responsive QR Code Card using HTML and CSS. This was my first Frontend Mentor challenge, and I learned how to use Flexbox for layout and make the design pixel-perfect. I also deployed the project live using Netlify, which was a great learning experience.
Next time, I would spend more time planning the layout before writing code. I’d also like to use CSS variables for colors and fonts to make the code more maintainable. Additionally, I want to explore adding animations or hover effects to make the design more interactive.
What challenges did you encounter, and how did you overcome them?One of the main challenges I faced was making the QR Code Card responsive. At first, the layout looked good on desktop but broke on mobile. I overcame this by using media queries to adjust the card’s width and font sizes for smaller screens.
Another challenge was positioning the elements correctly. I struggled with aligning the text and image perfectly. To solve this, I referred to Flexbox documentation and used justify-content and align-items to center the card and its content.
Finally, deploying the project was a bit confusing at first. I had never used Netlify before, but I followed a tutorial and successfully deployed my site. It was a great learning experience!
What specific areas of your project would you like help with?I’d like help with improving the responsiveness of my QR Code Card. Does it look good on all screen sizes, and are there better ways to implement media queries?
I’m also curious about how I can make my CSS code more organized and maintainable. Should I use CSS variables or a preprocessor like SASS?
Finally, I’d like feedback on accessibility. Are there any improvements I can make to ensure my project is accessible to all users?

HTML:
-
You don't need to wrap the image in a
<div>
. -
Remove the
width
attribute on the image. -
The alt text must also say where it leads(the frontendmentor website). A good alt text would be "QR code leading to the Frontend Mentor website."
-
"Improve your front-end skills by building projects" is a heading. I would make it a
<h2>
- a page should only have one<h1>
, reserved for the main heading. As this is a card heading, it would likely not be the main heading on a page with several components.
CSS:
-
Make a habit of including a modern CSS Reset at the top of the stylesheet.
-
I recommend adding a bit of
padding
, for example16px
, on thebody
, to ensure the card doesn't touch the edges on small screens. -
Use the style guide to find the correct
background-color
, and move it frommain
tobody
. -
Use the style guide to find the correct
font-family
, and remember to specify fallback fonts,in case the font doesn't load on the user's device:font-family: 'Outfit', system-ui, sans-serif;
. Thefont-family
should not be set on*
, but instead on thebody
. -
On
main
, removewidth
, as it is 100% wide by default. Changeheight
tomin-height: 100svh
- this way, the content will not get cut off if it grows beneath the viewport. -
Remove the
width
inpx
on the card. We rarely want to give a component a fixed size, as we need it to grow and shrink according to the screen size. -
We do want to limit the width of the card, so it doesn't get too wide on larger screens. To solve this issue, give the card a
max-width
of around20rem
. -
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. -
On the image, add
display: block
,height: auto
andmax-width: 100%
- the max-width prevents it from overflowing its container. Without this, an image would overflow if its intrinsic size is wider than the container.max-width: 100%
makes the image shrink to fit inside its container.
