Window size

There are three ways to determine the size of the browser window (the viewport of the browser, excluding toolbars and scroll bars).

For Internet Explorer, Chrome, Firefox, Opera, and Safari:

    • Window.innerheight-Interior height of the browser window
    • Window.innerwidth-Interior width of the browser window

For Internet Explorer 8, 7, 6, 5:

    • Document.documentElement.clientHeight
    • Document.documentElement.clientWidth

Or

    • Document.body.clientHeight
    • Document.body.clientWidth

Practical JavaScript scenarios (all browsers included):

Instance 
var w=window.innerwidth| | document.documentelement.clientwidth| | Document.body.clientwidth;var h=window.innerheight| | document.documentelement.clientheight| | Document.body.clientHeight;

To edit your code:

<! DOCTYPE html>

<body>

<p id= "Demo" ></p>

<script>

var W=window.innerwidth | | Document.documentElement.clientWidth | | Document.body.clientWidth;

var H=window.innerheight | | Document.documentElement.clientHeight | | Document.body.clientHeight;

X=document.getelementbyid ("demo"); X.innerhtml= "Browser's internal window width:" + w + ", Height:" + H + ". "

</script>

</body>

View results:

Browser's internal window width: 752, Height: 400.
