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 image has meaning, so it must have proper alt text. Write something short and descriptive, without including words like "image" or "photo". Screen readers start announcing images with "image", so an alt text of "image of qr code" would be read like this: "image, image of qr code". 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.
- Your code is more readable if you indent child elements, so your structure should look like this:
```
<main>
    <div class="wrapper">
        <img src="./images/image-qr-code.png" alt="QR code leading to the Frontend Mentor website.">
        <h2>Improve your front-end skills by building projects</h2>
        <p>Scan the QR code to visit Frontend Mentor and take your coding skills to the 
        next level</p>
    </div>
</main>
```
CSS:
- It is best practice to write CSS in a separate file, often called style.css. Create one in the same folder as the index.html, and link to it in the <head>: <link rel="stylesheet" href="style.css">.
- Including a CSS Reset at the top is good practice.
- Remember to specify a fallback font:font-family: 'Outfit',sans-serif;
- You only need to set font-family on the body, and remove it elsewhere. The children of body will inherit the value.
- I recommend adding a bit of padding, for example 16px, on the body, to ensure the card doesn't touch the edges on small screens.
- On the body, change height to min-height: 100svh - this way, the content will not get cut off if it grows beneath the viewport.
- max-width on the card should be in rem. Around 20rem will work fine.
- 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.
- line-height must also never be in px. It's common to use a unitless number, for example 1.5 - which means the line-height is 1 and a half times bigger than the 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.
- Paragraphs have a default value of font-weight: 400, so there is no need to declare it.
- On the image, remove the width in px - setting fixed sizes is rarely a good idea for responsive components. Instead, add height: auto, 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.
