I'd like some help with centering divs, I found kind of easy with the horizontal centering but it was difficult when I tried vertical. Any advice or comment about what I did would be really appreciated. Also sorry for my english in advanced, it's not my first language (:

    Hello there 👋. Congratulations on successfully completing the challenge! 🎉

    • I have other recommendations regarding your code that I believe will be of great interest to you.

    CSS 🎨:

    • Let me explain, How you can easily center the component for better layout without usage of absolute positioning.

    • We don't need to use absolute to center the component both horizontally & vertically. Because using absolute will not dynamical centers our component at all states

    • To properly center the component in the page, you should use Flexbox or Grid layout. You can read more about centering in CSS here 📚.

    • For this demonstration we use css Grid to center the component
    body {
    min-height: 100vh;
    display: grid;
    place-items: center;
    }
    
    • Now remove these styles, after removing you can able to see the changes
    .container {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, 10%);
    }
    

    • Now your component has been properly centered.

    .

    I hope you find this helpful 😄 Above all, the solution you submitted is great !

    Happy coding!

    Hello, you can add the <main> tag around around the container, which specifies the main content of a document.

    <main>
    <div class="container" >
    <div class="main-content">
          
    <h1>Stay updated!</h1>
    

    then modify your CSS to use flex and removing the position properties as follows:

    body {
    background-color: var(--darkSlateGrey);
    font-size: 16px;
    }
    main{
    display: flex;
    align-items: center;
    justify-content: center;
    height:100vh;
    }
    
    .container {
    background-color: var(--white);
    display: flex;
    width: 800px;
    height: 500px;
    padding: 20px;
    border-radius: 20px;
    }
    

    *** I added the correct background color, you may have to adjust your media query css

    In your CSS code, give body element height of 120 or 150vh by using media query with max-height: 400px; for screens with small heights so that your web app look good on small screens.

    you were using transform

    transform: translate(-50%, 10%);
    

    The correct way to center a div using the positioning property is

    transform: translate(-50%, -50%);    ✔

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.
