    Hi there 👋. Good job on completing the challenge ! I have some feedback for you if you want to improve your code.

    Answering your question:

    • You should use a CSS reset to remove the default browser styles and make your page look the same in all browsers.

    Your body's default margin causes the vertical scrollbar to appear.

    Popular CSS resets:

    • Normalize.css
    • Reset CSS

    HTML:

    • Since this component involves scanning the QR code, the image is not a decoration, so it must have an alt attribute. The alt attribute should explain its purpose. e.g. QR code to frontendmentor.io

    I hope you find it useful! 😄 Above all, the solution you submitted is great!

    Happy coding! 🎄

    You have many ways to hiding the scroll - this is one, set the min-height to 90vh

    main {
        min-height: 90vh;
    }

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.
