For example have a look at this website,I am wondering how an application like this would work.From what I understand, resolution awareness is not there with the webpage generator, but with the browser (webpage renderer). How does this work, then?
What allows a web application to find out the resolution of the screen when the page is rendered?
website;browser;resolution
The page you refer to uses JavaScript.If you view source, you'll see the following script:<SCRIPT language=JavaScript><!--height = screen.height;width = screen.width;res = document.getElementById ('resolutionNumber');res.innerHTML = width +  X  + height;if (res == null){    alert (hello);}//--></SCRIPT>
