Qr-code component with Flexbox

HTML:

• Remove the <article>, you only need the .card div inside the <main>.

• In the alt text, change qr-code to qr code.

• Delete .attribution if you're not going to include it. If you do, it should be a <footer>, and you need to use <p> for the text inside.

CSS:

• Including a CSS Reset at the top is good practice.

• Add around 1rem of padding on the body, so the card doesn't touch the edges on small screens.

• On the body, change height to min-height - this way, the content will not get cut off if it grows beneath the viewport.

• Remove all widths and heights in px.

• Move border and align-items from .content to .card. Remove the remaining properties on .content.

• Remove the properties on .content-card, as the <article> should be removed from the HTML.

• Add a max-width of around 20rem on the card, to prevent it from getting too wide on larger screens.

• 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.

• Paragraphs have a default value of font-weight: 400, so there is no need to declare it.

• Remove margin and padding on .card-img. On the image itself, add display: block and max-width: 100% - the max-width prevents it from overflowing its container.

• To create the space between the image and the edge of the card, set padding on all 4 sides of the card: padding: 1rem;.
