QR code component using HTML and CSS Flex

Replace<div id="card">with the main tag, <h2> with <h1> and <div class="attribution"> with the footer tag to fix the accessibility issues. click here for more on web-accessibility and semantic html

To center #card on the page using flexbox, replace the height in the body with min-height: 100vh.

Give h1 and p the same font-size of 15px, text-align: center, the same margin-left, margin-right and margin-top values. Give p a margin bottom value.

Use relative units like rem or em as unit for the padding, margin, width values and preferably rem for the font-size values, instead of using px which is an absolute unit. For more on CSS units Click here

Hope am helpful.

Well done for completing this challenge. HAPPY CODING

The design is simple and straightforward, with a clear focus on the QR code component.

The color palette is appropriate, and the font choices are legible, but don't like the layout of the text

Overall, the design seems to be well executed and effective in presenting the QR code component.

good luck
