    👾Hello again Doine, Congratulations on completing this challenge!

    I've some suggestions for your old solution:

    1.Don’t use id to give the style of your elements, its not a good idea because id its a too much specific selector used for forms and Javascript code. Instead, use class for styling and let the id for much specific stuff. Its also not advisable to use IDs as CSS selectors because if another element in the page uses the same/similar style, you would have to write the same CSS again. Even if you don't have more than one element with that style right now, it might come later.

    2.Replace the <h3> heading with <h1> note that this title is the main heading for this page and every page needs one h1 to show which is the most important heading. Use ever the sequence h1 h2 h3 h4 h5 to show the hierarchy of your titles in level of importance, never jump a level.

    3.The html structure is fine and works, but you can reduce at least 20% of your code cleaning the unnecessary elements, you start cleaning it by removing some unnecessary <div>. For this solution you wrap everything inside a single block of content using <div> or <main> (better option for accessibility) and put inside the whole content <img> / <h1> and <p>.

    <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!

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.
