if you're putting your script inside <script></script> tags inside the <body></body> tags, put it at the bottom, just before the closing </body> tag, so that the html is loaded properly.
<body>
your html...
...
...
<script>
your js
</script>
</body>
</html>

Rondell Nagassar You're running the script before the HTML is parsed, so your script cannot find the element by the ID.
Think of it as searching for a pen from a box holding different kinds of items. If the pen isn't even in the box, how can you find it?
Move the script tag along with its code to the end of body(after the HTML code). Or just use external JavaScript(move the js code to the JS tab). If you do that, or still want to keep the script content before the HTML at start of body, make sure to wrap it in an onload event handler:
window.onload = () => {
// your javascript code
}

You can only access the html elements with Javascript once the body is fully loaded.
Wrap your Javascript with
window.onload = () => {
...
}
To ensure that the code is only executed once the DOM is loaded.

Afnan Irtesum Chowdhury. Or, do you mean that I tried running Java code at the top of the HTML section so it comes like I'm running code without HTML? Like I'm doing things backwards? I'll try it now
