qr-code using html and css

Hey. Good job! Here's my feedback for you mate.

• Yep. You can target both paragraph using a common class and add styles that they share. However you should have not added two paragraphs, instead you could have used an h1 for the big boi and a paragraph for the small one.
• Your markup should have an h1 which would be the one I mentioned.
• You images must have alt attributes, you can leave them empty if the image is used for decoration.
• I think you should have used CSS variables to store the theme from the the style guide.
• For centering your content I would have coded something like this.

body {
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  gap: 7.5rem;
  font-family: 'Outfit', sans-serif; /* apply the font globally here */
  min-height: 100vh;
}

And removed the margin from the #container selector.

Hope this helps mate. Have a great day!
