    Your code has a few redundant elements. You can specify the centering directly in the body. flex and align-item: center is enough. Your .container doesn't need it anymore. The @media are completely unnecessary in this application. Just define your .qrcode with a width: min(90vw, 375px) and margin-inline: auto. This will center your element horizontally and your align-items in the body will be responsible for the vertical alignment. width:min(90vw, 375) means that depending on the viewport the smaller of the two values is used. On a narrow screen the width will be 90% of the viewport width, but with more space the element will grow to a maximum of 375px (or if you want to go bigger here, of course to a larger value). This way you need very little code and don't have to use unnecessary @mediaqueries.

    Of course you have to pay attention to the warnings of the accessibility report.

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.
