Mobile-first solution using CSS Grid and Flexbox

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

Give h1 and p the same font-size of 15px which is 0.9375rem, text-align: center, the same margin-left, margin-right and margin-top values. Give p a margin bottom value.

There is no need to give the body a height value, padding and margin: 0 auto.

To center .card on the page using flexbox or grid instead of margin, add min-height:100vh; display: flex; align-items: center: justify-content: center; or min-height:100vh; display: grid place-items: center to the body.

USING FLEXBOX:
body{
min-height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}

USING GRID:
body{
min-height: 100vh;
display: grid;
place-items: center;
}

For a responsive content give .card a fixed max-width value and a padding value for all the sides. max-width: 320px which is 20rem and padding: 1rem which is 16px.

Give the img a max-width of 100% for a responsive image instead of width and a border-radius value.

Hope am helpful.

Well done for completing this challenge. HAPPY CODING

Hello there 👋. Congratulations on successfully completing the challenge! 🎉

• I have other recommendations regarding your code that I believe will be of great interest to you.

HTML 🏷️:

• This solution generates accessibility error reports due to non-semantic markup, which lack landmark for a webpage

• So fix it by replacing the element <div class="card"> the with semantic element <main> along with <div class="attribution"> for <footer> a in your index.html file to improve accessibility and organization of your page.

• What is meant by landmark ?, They used to define major sections of your page instead of relying on generic elements like <div> or <span>

• They convey the structure of your page. For example, the <main> element should include all content directly related to the page's main idea, so there should only be one per page

I hope you find this helpful 😄 Above all, the solution you submitted is great !

Happy coding!

You can try use variables in css! I hope this helps!
