    Hi, nice to have you around! Welcome to Frontend Mentor Coding community Your solution looks great, you can still do some things to it:

    • replace the <h2> containing the main title 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 the sequence h1 h2 h3 h4 h5 to show the hierarchy of your titles in the level of importance, never jump a level.
    • you can use the <main> instead of using <section>.
    • for measurement you can use ruler tool from Photoshop.

    I hope it will help you, Enjoy coding!

    👾Hi Moh, congratulations on your solution!👋 Welcome to the Frontend Mentor Coding Community!

    Great solution and a great start! From what I saw you’re on the right track. I’ve few suggestions for you that you can consider adding to your code:

    • Use <main> instead of a simple <div> this way you improve the semantics and accessibility showing which is the main block of content on this page. Remember that every page should have a <main> block and that <div> doesn't have any semantic meaning.
    • Replace the <h2> containing the main title 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 the sequence h1 h2 h3 h4 h5 to show the hierarchy of your titles in the level of importance, never jump a level.
    • Add a margin of around margin: 20px to avoid the card touching the screen edges while it scales down.
    • Use relative units as rem or em instead of px to improve your performance by resizing fonts between different screens and devices. These units are better to make your website more accessible. REM does not just apply to font size, but to all sizes as well.

    Here's my solution for this challenge if you wants to see how I build it: https://www.frontendmentor.io/solutions/qr-code-component-vanilla-cs-js-darklight-mode-nS2aOYYsJR

    ✌️ 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, SASS, 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.
