html - Use: Need Javascript code that gets the inner width/height of screen onload into width/height style variables -


i find innerwidth , innerheight of screen via javascript, , place values width , height variables of body class in style area (css) of html. example:

<style>   body { background-image: url("images/hello.jpg");           background-repeat: no-repeat; background-color: brown;           width: valuew; height: valueh;} </style>
