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">
**Your Paragraph Comes Here**
</div>

FaceScroll自定义滚动条

希望能有所帮助

有一种方法可以将自定义滚动条应用于HTML文档中的自定义div元素。这里有一个有用的例子。https://codepen.io/adeelibr/pen/dKqZNb但作为一个要点。你可以这样做。

<div class="scrollbar" id="style-1">
  <div class="force-overflow"></div>
</div>

CSS文件是这样的。

.scrollbar
{
  margin-left: 30px;
  float: left;
  height: 300px;
  width: 65px;
  background: #F5F5F5;
  overflow-y: scroll;
  margin-bottom: 25px;
}

.force-overflow
{
  min-height: 450px;
}

#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;
}

试试吧

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。

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. Gumbo beet greens corn soko endive gumbo gourd. Parsley shallot courgette tatsoi pea sprouts fava bean collard greens dandelion okra wakame tomato. Dandelion cucumber earthnut pea peanut soko zucchini. </div>

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。

* { box-sizing: border-box; font-family: sans-serif; } div { width: 15rem; height: 8rem; padding: .5rem; border: 1px solid #aaa; margin-bottom: 1rem; overflow: auto; } .box::-webkit-scrollbar { width: .8em; } .box::-webkit-scrollbar-track { box-shadow: inset 0 0 6px rgba(0, 0, 0, .3); } .box::-webkit-scrollbar-thumb { background-color: dodgerblue; } <div class="box"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

参考: 如何创建自定义滚动条

在Firefox +64中只使用CSS

.mycoldiv{
    scrollbar-color: white rebeccapurple;
    scrollbar-width: thin;
    display: block;
    height:400px;
    overflow-x: auto;
}
