下面是一个适用于Chrome和Safari的webkit示例:

CSS:

::-webkit-scrollbar 
{
    width: 40px;
    background-color:#4F4F4F;
}

::-webkit-scrollbar-button:vertical:increment 
{
    height:40px;
    background-image: url(/Images/Scrollbar/decrement.png);
    background-size:39px 30px;
    background-repeat:no-repeat;
}

::-webkit-scrollbar-button:vertical:decrement 
{
    height:40px;
    background-image: url(/Images/Scrollbar/increment.png);    
    background-size:39px 30px;
    background-repeat:no-repeat;
}

输出:

我尝试了很多JS和CSS滚动，我发现这很容易使用，并在IE、Safari和FF上进行了测试，效果很好

正如@ theblufox所言

下面是它的工作原理

将下面的脚本添加到

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
<script type="text/javascript" src="jquery.ui.touch-punch.min.js"></script>

<script type="text/javascript" src="facescroll.js"></script>

<script type="text/javascript">
    jQuery(function(){ // on page DOM load
        $('#demo1').alternateScroll();
        $('#demo2').alternateScroll({ 'vertical-bar-class': 'styled-v-bar', 'hide-bars': false });  
    })
</script>

在这段你需要滚动的地方

<div id="demo1" style="width:300px; height:250px; padding:8px; resize:both; overflow:scroll">

</div>

DEMO

Webkit浏览器(如Chrome, Safari和Opera)支持非标准的::-webkit-scrollbar伪元素，它允许我们修改浏览器滚动条的外观。

注意:Firefox、IE和Edge不支持::-webkit-scrollbar。
