QR code component (FLEX)

Replace <section> with the main tag, <h2><p> with <h1> and <h3><p> with <p> to fix the accessibility issue. for more on semantic html visit https://web.dev/learn/html/semantic-html/

Give .QR a fixed width instead of a percentage width, the fixed width can either be 300px or 400px. Add min-height:100vh to the section/the main to center .QR on the page using flexbox, instead of giving it a margin-top value. There is no need to give .QR a margin value.

Use rem or em as unit for the padding, margin, width and preferably rem for the font-size for more on this watch this https://youtu.be/N5wpD9Ov_To there is no need to give the text a font-size.

Hope am helpful Happy coding.

HEY YOUXIE!

Congratulations on completing your first challenge

Concerning your question about centering, One of the best ways for centering would be to give the body a height of 100vh height:100vh then a display of grid display: grid and then using the code place-items: center

There is no need to place a p inside an h2 or h3, this will get rid of the error on your HTML report.

You will also need to increase the width of your parent container and set a max-width for as well so that it does not constantly increase in size.

HOPE I COULD BE OF HELP :)

HAPPY CODING!
