qr-code-component-main

HTML:

• Every webpage needs a <main> that wraps all of the content, except for <header> and footer>. This is vital for accessibility, as it helps screen readers identify a page's "main" section. Wrap the card in a <main>.

• The alt text must also say where it leads(the frontendmentor website). A good alt text would be "QR code leading to the Frontend Mentor website."

• I would change the heading to a <h2> - a page should only have one <h1>, reserved for the main heading. As this is a card heading, it would likely not be the main heading on a page with several components.

• Do not use <br> to force text onto a new line. The text should flow naturally, and all styling, including space between elements, should be done in the CSS.

• Wrap the footer text in a <p>.

CSS:

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

• I would recommend adding 1rem of padding on the body, to ensure 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. Also, remove the width and add gap: 2rem, to create space between the main and the footer. And you don't need font-weight: 400, as that is the default.

• Remove all widths and heights in px. We rarely want to give a component a fixed size, as we want it to grow and shrink according to the screen size.

• We do want to limit the width of the card, so it doesn't get too wide on larger screens. Give the card a max-width of around 20rem to solve this issue.

• 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.

• letter-spacing must also not be in px. You can use em, where 1em equals the element's font size.

• 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.

• Likewise, set font-family on he body, and remove it anywhere else. Remember that typographic properties usually get inherited through an element's ancestor.

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

• On the image, add display: block and max-width: 100% - the max-width prevents it from overflowing its container. Without this, an image would overflow if its intrinsic size is wider than the container. max-width: 100% makes the image shrink to fit inside its container. Remove flex-shrink, it is not needed. And it's usual to set height: auto on images.

• On the footer , align-items: flex-end and justify-content: end doesn't work unless you also declare display: flex. However, it is not needed, so I would delete those styles altogether.

• As the design doesn't change, there is no need for any media queries. When you do need them, they should be in rem or em, not px. Also, it is common practice to do mobile styles first and use media queries for larger screens.

it is good but you can make the footer in the end of the screen and make text vertically start from same point
