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 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>

You want to be the best, you MUST put the long yards in! Nothing comes easy in life so stop wishing and start DOING! So many people would rather bitch and moan than help themselves. Dont be one of those negative drainers, start today, make a small change and keep going forwards with this attitude!

Random CSS Property

content-visibility

The content-visibility CSS property controls whether or not an element renders its contents at all, along with forcing a strong set of containments, allowing user agents to potentially omit large swathes of layout and rendering work until it becomes needed. Basically it enables the user agent to skip an element's rendering work (including layout and painting) until it is needed — which makes the initial page load much faster.
