Blog preview card in HTML and CSS with Flexbox and Media queries

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 the "main" section of a page. Replace <section> with <div class="card">, and wrap that in a <main>.

• Do not use "image" in the alt text, as that will make screen readers announce "image" twice.

• "Learning" is not a <button>, as it doesn't trigger an action. Make it a <p>.

• Headings should always be in order, so you should never start with a <h5>. And "Published" is not a heading, so make it a <p>. Also, wrap the date in a <time> tag, like this:<p>Published <time datetime="2023-12-21">21 Dec 2023</time></p>.Read more about the <time> element here.

• Change the profile image alt text to "Headshot of Gary Hooper" - this is more descriptive than just "Avatar".

• "Greg Hooper" is a <p>, not a heading. If it were a heading, it would be a <h2>, as I mentioned the heading hierarchy above.

• .attribution should be a <footer>, and you should use <p> for the text inside.

CSS:

• Your CSS Reset is missing essential rules like max-width: 100% on <img>, to prevent images from overflowing their container. I like to use the reset from Andy Bell.

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

• Remove the margin on the card.

• 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;

• Remove width and height on "Learning". Give it a display: inline-block and some padding.

• max-width on card should be in rem.

• Remove the width and height on the card. Never limit the height of elements containing text!

• Use 1.5 for line-height instead of 150%. You can set it on body, and the elements will inherit the value, there's no need to declare it on every element.

• 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.

• Media queries must be in rem, and it is common to do mobile styles as the default.
