you can use vw approximate window width (its not window width, 99% of time work). css3, though. units vhand vw act percentage of viewport size. more info here: https://developer.mozilla.org/en/docs/web/css/length

heres example:

div { width: 100vw; } /* div width of viewport, or browser window (most of time)*/
