I created two article, but this app say me NO, I can`t see them. Why? What is wrong?

<main>
    <!--First section-->
        <section id="upcoming-events">
            <h2>Upcoming Events<h2>
            <article>
            <h3>Why Combine Sports Viewing and Movie Nights?</h3>
                <p>Not everyone loves sports, and not everyone loves movies - but almost everyone enjoys one or the other! By combining both activities, you're creating an event that appeals to way more people.</p>
            </article>
            <article>
                <h3>Broadening Your Event's Appeal</h3>
                <p>This approach is constructive for March Madness when multiple games happen throughout the day. Instead of a group that disperses between matchups, you can maintain a consistent atmosphere by showing a basketball movie between the afternoon and evening games. Trust us, it works!</p>

        </section>

It would help if you posted a link to the Step or project.

What you’ve written is not enough code for this project. Do you have more code?

Hi @serega49 !

Welcome to the forum!

The reason why you are not seeing certain elements because you have syntax errors in your code.

It looks like you are missing the closing main tag.
But also, you have an issue here

same issue with closing tags.

This early into your learning I would suggest running your code frquently through an HTML validator to help you catch these errors.

HTML is very forgiving in the sense that it won’t crash the page if you have errors like this.
However, it will cause issues with elements not showing up correctly and issues with your css.

Hope that helps
