    👾Hello Kingsley , congratulations for your first solution!👋 Welcome to the Frontend Mentor Coding Community!

    Great start and great first solution! You’ve done really good work here putting everything together, I’ve some suggestions you can consider applying to your code: Something I've noticed in your code is that in many occasions you've added some <div> to wrap contents that don't really need to be inside of a div block. Note that for this challenge all you need is a single block to hold all the content, can be <div> or <main> if you want to use a semantic tag to wrap the content, the cleanest structure for this challenge is made by a block of content with div/main and all the content inside of it (img, h1 and p) without need of any other div or something. See the structure below:

    <body>
    <main>
    <img src="./images/image-qr-code.png" alt="Qr Code Image" >
     <h1>Improve your front-end skills by building projects</h1>
    <p>Scan the QR code to visit Frontend Mentor and take your coding skills to the next level</p>
    </main>
    </body>
    

    ✌️ I hope this helps you and happy coding!

    Hi Kingsley, congratulations on completing the challenge, great job! 😁

    Some little tips for optimizing your code:

    • use article tag instead of main tag to the container card for improve the Accessibility. Main tag is for wrap the all main page content
    • remove all margin from card class
    • use flexbox to the body to center the card. Read here -> best flex guide
    • after, add min-height: 100vh to body because Flexbox aligns child items to the size of the parent container
    • instead of using px use relative units of measurement like rem -> read here

    Hope this help! Happy coding 😉

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit all CSS, SCSS and Less files in your repository.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.

How does the JavaScript validation report work?

When a solution is submitted, we use eslint to run an automated check on the JavaScript code.

The report picks out common JavaScript issues such as not using semicolons and using var instead of let or const, among others.

The report will audit all JS and JSX files in your repository. We currently do not support Typescript or other frontend frameworks.
