javascript - Adding background img if screen resolution width >1028 -

hi guys,

i'm new javascript. have pretty simple script wrote add together background image if screen resolution width bigger 1028px.

unfortunately, after trying (on computer, 800x600 resolution), doesn't work.

i'm not looking stretch image, add together if screen resolution width bigger or equal 1024.

here code:

<script language="javascript"> <!-- document.write('<style type="text/css">div#container_header_body {background-image:url(\''); if (screen.width<1024) { document.write('none;'); } else { document.write('images/mmmgirl.png'); } document.write('\');</style>'); //--> </script> <link rel="stylesheet" type="text/css" href="stylesheet.css" />

can give me insight i'm doing wrong?

thanks much. i've learned lot place.

try this jsfiddle:

var screenwidth = screen.width, container = document.getelementbyid('container_header_body'); console.log(screenwidth); if (screenwidth > 1024) { container.style.backgroundimage = 'url(http://oddanimals.com/images/lime-cat.jpg)'; } else { container.style.backgroundimage = 'none'; }
