Hi John, here is some feedback I hope you find clear and helpful.

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.

• The alt text must also say where it leads(frontendmentor website).

• "Improve your" is a heading, so change it to a <h1>.

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.

• Remove the positioning and transform properties.

• To center the card horizontally and vertically, use Flexbox on the body:

display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
min-height: 100svh;
gap: 2rem;

• Remove all widths in px.

• 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.

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

• Put align-items: center on the card, and remove align-self: center from the image and the text - this is much more efficient!

• On the image, 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.

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