Answer 1

A non-jQuery way to get the available screen dimension. Use window.screen.availWidth/Height .

alert(window.screen.availWidth);
alert(window.screen.availHeight);

http://www.quirksmode.org/dom/w3c_cssom.html#t10 :

availWidth and availHeight - The available width and height on the screen (excluding OS taskbars & such).
