    Hi, great job!

    I noticed that you used an <h2> tag directly. While HTML allows you to use <h2> tags without a preceding <h1>, it is considered best practice for accessibility and SEO to have at least one <h1> tag in your document to establish a clear content hierarchy. It's best practice to start with an <h1> tag and use subsequent heading tags (<h2>, <h3>, etc.).

    Keep up the good work and happy coding!

    Hey, good solution 😉.

    I have a little tip for you. In most cases you don't need a media query for cards, like in this case. Add these lines to the classic .card and it should have the same effect.

    margin: 1rem;
    max-width: 350px;
    

    With these two lines you have made the card responsive for all devices. The max width means that the card cannot get larger. The margin, in contrast, is the distance to the edge of the screen when you make the browser window smaller. Now you can delete the media query.

    I hope I could help you

    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 1st-party linked stylesheets, and styles within <style> tags.

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.
