css是无法实现的，您要横向滚动只有通过js监听页面的拖动事件才行。给你个插件可以研究研究，这插件能让你体验到win8切换的效果。
如果你非要用滚轮来响应横向滚动 你还是得用js监听滚轮，给滚轮绑定一个事件，没次滚动都使div 内容向某个方向animate移动一个固定距离
通过此函数可以获取到鼠标滚动事件，然后做平移就好了/** Event handler for mouse wheel event.
*鼠标滚动事件
*/
var wheel = function(event) {
var delta = 0
if (!event) /* For IE. */
event = window.event
if (event.wheelDelta) { /* IE/Opera. */
delta = event.wheelDelta / 120
} else if (event.detail) {
/** Mozilla case. */
/** In Mozilla, sign of delta is different than in IE.
* Also, delta is multiple of 3.
*/
delta = -event.detail / 3
}
/** If delta is nonzero, handle it.
* Basically, delta is now positive if wheel was scrolled up,
* and negative, if wheel was scrolled down.
*/
if (delta)
handle(delta)
/** Prevent default actions caused by mouse wheel.
* That might be ugly, but we handle scrolls somehow
* anyway, so don't bother here..
*/
if (event.preventDefault)
event.preventDefault()
event.returnValue = false
}
/** Initialization code.
* If you use your own event management code, change it as required.
*/
if (window.addEventListener) {
/** DOMMouseScroll is for mozilla. */
window.addEventListener('DOMMouseScroll', wheel, false)
}
/** IE/Opera. */
window.onmousewheel = document.onmousewheel = wheel
/** This is high-level function.
* It must react to delta being more/less than zero.
*/
var handle = function(delta) {
var random_num = Math.floor((Math.random() * 100) + 50)
if (delta <0) {
// alert("鼠标滑轮向下滚动：" + delta + "次！")// 1
$("btn_next_pic").onclick(random_num)
return
} else {
// alert("鼠标滑轮向上滚动：" + delta + "次！")// -1
$("btn_last_pic").onclick(random_num)
return
}
}
可以使用DIV+CSS+JS实现不间断横向滚动代码，具体代码如下：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html charset=gb2312" />

<body>
<style>
.scroll_div {width:600px height:49pxmargin:0 auto overflow: hidden white-space: nowrap background:#ffffff}
.scroll_div img {width:120pxheight:49pxborder: 0margin: auto 8px }
#scroll_begin, #scroll_end, #scroll_begin ul, #scroll_end ul, #scroll_begin ul li, #scroll_end ul li{display:inline}/* 设置ul和li横排 */
</style>
<script language="javascript">
function ScrollImgLeft(){
var speed=20
var scroll_begin = document.getElementById("scroll_begin")
var scroll_end = document.getElementById("scroll_end")
var scroll_div = document.getElementById("scroll_div")
scroll_end.innerHTML=scroll_begin.innerHTML
function Marquee(){
if(scroll_end.offsetWidth-scroll_div.scrollLeft<=0)
scroll_div.scrollLeft-=scroll_begin.offsetWidth
else
scroll_div.scrollLeft++
}
var MyMar=setInterval(Marquee,speed)
scroll_div.onmouseover=function() {clearInterval(MyMar)}
scroll_div.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
}
</script>
