Responsive QR code component using html and css

What are you most proud of, and what would you do differently next time?

Working on this project helped me reinforce my understanding of Flexbox and CSS custom properties. I also practiced creating a responsive design that adapts to different screen sizes.

Here's a snippet of code that I'm proud of:

.qr-card {
  display: flex;
  padding: var(--spacing-200) var(--spacing-200) var(--spacing-500) var(--spacing-200);
  flex-direction: column;
  align-items: flex-start;
  gap: var(--spacing-300);
  border-radius: 20px;
  background: var(--color-white);
  box-shadow: 0px 25px 25px 0px rgba(0, 0, 0, 0.05);
}
