    Hi there! 👋

    Congratulations on finishing this challenge! 👏

    Some recommendations from me.

    • I would not recommend wrapping the img element with picture element if only one image is used for all screen sizes. You want to use picture element for the following reasons (source: MDN documentation).
      • Art direction. Cropping or modifying images for different media conditions (for example, loading a simpler version of an image which has too many details, on smaller displays).
      • Offering alternative image formats, for cases where certain formats are not supported.
    • You can make this website fully responsive without any media queries. The styling for the card is consistent on all screen sizes. Also, I suggest using max-width to limit the width of the card. This way, the card is allowed to shrink if ever needed which means it is way more responsive.
    • I recommend simplifying the HTML markup by not using any div elements.

    Hope this helps. 🙂

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.
