How do Self-Closing JSX Tags Work?

So in JSX all the tags must be closed, other wise it can break the element.

for example: <div> must have a closing </div> and also for elements like <br> and <hr> must include the /.

So make sure you do your single elements with a / at the end, like <br /> and <hr /> rather than the normal html versions of them. 

HTML

<div id="root"></div>

Scripts

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/18.0.0-alpha-5fa4d79b0-20211008/umd/react.production.min.js" integrity="sha512-5PVmWGoNJocWPdQJmJd1aRbz3cFcFgXctWKLWcitqtgX64jF+ttfg9g2oLltmeQ1HUo3gT6QchaMK3h+S+JG4Q==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

<script type="text/babel">
const JSX = (
  <div>
    <h2>Welcome to React!</h2> <br />
    <p>Be sure to close all tags!</p>
    <hr />
  </div>
);
ReactDOM.render(JSX, document.getElementById('root'))
</script>

Random CSS Property

<display-inside>

These keywords specify the element's inner display type, which defines the type of formatting context that lays out its contents (assuming it is a non-replaced element). These keywords are used as values of the display property, and can be used for legacy purposes as a single keyword, or as defined in the Level 3 specification alongside a value from the <display-outside> keywords.
