    Hi Gastón, congratulations on your new challenge! You had done a great job !!! I took a look at your code and I have some tips for you. To avoid the HTML Issues Section lacks heading. Consider using h2-h6 elements to add identifying headings to all sections.

    Document should have one main landmark

    Context: <html lang="en">

    Ensure that the page or at least one of its frames contains a level-one heading.

    Generally, it is a best practice to ensure that the beginning of a page's main content starts with a h1 element, and also to ensure that the page contains only one h1 element.

    Usually the best practice is to start the main content of a web page with a level 1 heading (h1), with no other headings before this high-level heading. Mark the sub-sections of the page as level 2 headings (h2). If the level 2 sections contain sub-sections, mark these children as level 3 sections (h3) and so on.

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.
