You can use this type of jquery and Css code. and add it to your scroll div

$(document).ready(function() {
var bodyWidth = $(window).width();
$('.scrolldiv').css('width',bodyWidth);
});
</script>
CSS
.scrolldiv{
overflow:scroll;
}

If you want fluid view when resize u can also use this code
$(document).ready(function() {
getwidth();
});
$(window).resize(function() {
getwidth();
});
function getwidth()
{
var bodyWidth = $(window).width();
$('.scrolldiv').css('width',bodyWidth);
}
