Microsoft Internet Explorer and Netscape Navigator do this slightly differently, so you’ll need to first detect the browser type and then set up the following variables:
For Internet Explorer:
var BrowserHeight = document.body.clientHeight;var BrowserWidth = document.body.clientWidth;
For Netscape Navigator:
var BrowserHeight = window.innerHeight;var BrowserWidth = window.innerWidth;
With those variables in hand, you can lay out the page more effectively and reduce wasted space.
