finding browsing area height

[sirlink99]

I am making a website, and I would like to figure out what size the display portion of the browser is.

Here is more of an idea of what I mean

tabs and menu
widgets if they have any
browser window
bottom portion of web browser

I would like to know how to figure out the browser window height.

Thanks for your help.

this is js not php. PHP can't tell.

by doing a google search

function getDocHeight() {
    var D = document;
    return Math.max(
        Math.max(D.body.scrollHeight, D.documentElement.scrollHeight),
        Math.max(D.body.offsetHeight, D.documentElement.offsetHeight),
        Math.max(D.body.clientHeight, D.documentElement.clientHeight)
    );
}

console.log(getDocHeight());
