.className::-webkit-scrollbar {
  width: 10px;
  background-color: rgba(0,0,0,0);
}

.className::-webkit-scrollbar-thumb {
  background: rgba(255, 255, 255, 0.5);
  border-radius: 5px;
}

给了我一个漂亮的手机。

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:

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。

参考: 如何创建自定义滚动条

Firefox新版本(64)支持CSS滚动条模块级别1

.scroller { width: 300px; height: 100px; overflow-y: scroll; scrollbar-color: rebeccapurple green; scrollbar-width: thin; } <div class="scroller"> Veggies es bonus vobis, proinde vos postulo essum magis kohlrabi welsh onion daikon amaranth tatsoi tomatillo melon azuki bean garlic.

简单的实现

<script type="text/javascript">
 $(document).ready(

  function() { 

    $("html").niceScroll();

  }

);
</script>

它是一个jQuery插件滚动条，所以你的滚动条是可控的，在不同的操作系统上看起来是一样的。

   #style-1::-webkit-scrollbar-track
{
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
    border-radius: 10px;
    background-color: #F5F5F5;
}

#style-1::-webkit-scrollbar
{
    width: 12px;
    background-color: #F5F5F5;
}

#style-1::-webkit-scrollbar-thumb
{
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
    background-color: #555;
