Mobile-first solution using CSS Flexbox.

Hi Nicolas. Here is some feedback.

HTML:

• The icons are decorative, meaning the alt text should be empty: alt="".

• "Learn More" would navigate to another page, hence it is not a button but a link.

• If you include the <footer>, its text should be wrapped in a <p>.

CSS:

• It's good practice to include a CSS Reset at the top.

• Remove margin, overflow and the position properties on the card container.

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

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

• Remove all widths and heights in px.

• Give the card container a max-width in rem, so it doesn't get 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.

• Add some padding on "Learn More".

• Media queries must be in rem.
