    Hi Felipe, good job! I took some time to look at your code and have some ideas for improving it:

    • add main tag and wrap the card for improve the Accessibility
    • remove all margin from card class
    • try to use flexbox to the body for center the card. Read here -> best flex guide
    • after, add min-height: 100vh to body because Flexbox aligns child items to the size of the parent container
    • instead of using px or % try to use relative units of measurement like rem -> read here

    Overall you did well 😉

    Hope this help and happy coding!

    Hello there, this is my first comment trying to feedback someone, I'm not an expert too I started not long ago so everyelse is reading this I hope leave a better feedback, I'm learning english aswell so I hope all I want to say its understandable...

    First of all, I learned or was taught that always try to use classes for styling. For example with h1 or p in your HTML you're not using classes and using a general selector in the stylesheet so you don't have unexpected errors with specificity, general bugs, etc.

    Second, I was taught that is better start styling mobile size first so you get styles for mobiles and desktop sizes.

    Everything else you've done a good job, keep the work, and keep an eye with the accesibilty issues :)

    Have a good day.

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.
