....Doesn't relate to window.onload....
It's
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<span id="page2">
<h1><div id="rocktxt2">Rock</div><div id="papertxt2">Paper</div><div id="scissorstxt2">Scissors</div>THE GAME!</h1>
</span>
<script>
var page2 = document.getElementById("page2").style.display = "none";
</script>
</body>
</html>
The problem
is
SL auto include <script> in <head> tag
While we need
to include <script> in <body> tag
You know what to do right?

😊 Yep window.onload Help a lot
Bc
<head> activate the javascript while element isn't loaded the page finished yet
But window.onload....after loaded finished now. => activate the function inside window.onload

window.onload = function(){
// put your js code here.
}

Your code is correct. There is a bug in Sololearn Playground. Refer to this JSFiffle link.

Note
If you comment js codes. You will see that js was making span invisible.

Change javascript code style display from "none" to "block"

Hi @Ani Naslyan
Jsfiddle already set the js code to onload type by default, whereas SL code playground, we have to set it by ourself.
This is not a bug on SL code playground.

Whenever you use document object, you have to set it inside window.onload, this function make sure that your elements are loaded before setting your element variables.

@Very
You are right, when we put js code together with html, got to include script tag.
But if the js code in js column, we have to put the code inside window.onload, whenever declare element variables.
Many beginners make this mistake due to not familiar with SL code playground structure.
