CSS自定义滚动条在div

如何通过CSS(层叠样式表)为一个div而不是整个页面自定义滚动条?

自定义滚动条无法使用CSS，您需要一些JavaScript魔法。

一些浏览器支持非规范的CSS规则，比如Webkit中的::-webkit-scrollbar，但这并不理想，因为它只能在Webkit中工作。IE也有类似的东西，但我认为他们不再支持它了。

最佳答案

我认为整合滚动条、CSS和浏览器兼容性方面的最新信息会很有帮助。

CSS支持滚动条

目前，还不存在跨浏览器滚动条CSS样式定义。我在最后提到的W3C文章有以下声明，最近更新(2014年10月10日):

一些浏览器(IE, Konqueror)支持'scrollbar-shadow-color'， 'scrollbar-track-color'等非标准属性。这些属性是非法的:它们既没有在任何CSS规范中定义，也没有被标记为专有属性(通过在它们前面加上"-vendor-")

微软

正如其他人提到的，微软支持滚动条样式，但仅限于IE8及以上版本。

例子:

.TA {
scrollbar-3dlight-color:gold;
scrollbar-arrow-color:blue;
scrollbar-base-color:;
scrollbar-darkshadow-color:blue;
scrollbar-face-color:;
scrollbar-highlight-color:;
scrollbar-shadow-color:
}

铬,Safari (WebKit)

同样，WebKit现在也有了自己的版本:

Firefox(壁虎)

从64版开始，Firefox通过属性scrollbar-color(部分，W3C草案)和scrollbar-width (W3C草案)支持滚动条样式。在这个答案中可以找到一些关于该实现的有用信息。

跨浏览器滚动条样式

JavaScript库和插件可以提供跨浏览器的解决方案。有很多选择。

这样的例子不胜枚举。最好的办法是到处搜索、研究和测试可用的解决方案。我相信你一定能找到符合你需要的工作。

防止非法滚动条样式

以防你想要防止滚动条样式没有正确地前缀"-vendor"， W3C的这篇文章提供了一些基本的说明。基本上，您需要将以下CSS添加到与浏览器关联的用户样式表中。这些定义将覆盖您访问的任何页面上无效的滚动条样式。

body, html {
scrollbar-face-color: ThreeDFace !important;
scrollbar-shadow-color: ThreeDDarkShadow !important;
scrollbar-highlight-color: ThreeDHighlight !important;
scrollbar-3dlight-color: ThreeDLightShadow !important;
scrollbar-darkshadow-color: ThreeDDarkShadow !important;
scrollbar-track-color: Scrollbar !important;
scrollbar-arrow-color: ButtonText !important;
}

Webkit滚动条在大多数浏览器上不支持。

CHROME上的支持

另一个方法是Jquery滚动条插件

它支持所有浏览器，易于应用

我尝试了很多插件，其中大多数不支持所有浏览器，我更喜欢< >强iScroll < / >强和< >强nanoScroller < / >强适用于所有这些浏览器:

  • Ie11 -> ie6
  • Ie10 - wp8
  • Ie9 - wp7
  • IE Xbox One
  • IE Xbox 360
  • 谷歌Chrome
  • 火狐
  • 歌剧
  • Safari

但 iScroll不工作与触摸!

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

将以下脚本添加到 

<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>

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。

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:

这是谷歌在它的一些应用程序中使用了很长时间的方法。在代码中看到，如果你应用下一个类，他们以某种方式隐藏滚动条在Chrome，但它仍然工作。

这些类是jfk-scrollbar， jfk-scrollbar-borderless和jfk-scrollbar-dark

我发现从滚动条中移除箭头很有用。截至2015年，它被用于谷歌地图在其材料设计UI的结果列表中搜索位置。

和许多人一样，我在寻找的东西是:

  • 在大多数现代浏览器中保持一致的样式和功能
  • 不是一些可笑的3000行臃肿的jQuery扩展cr*p

并初始化:

/* Track */
.mydiv::-webkit-scrollbar-track {

border-radius: 10px;
}
     

/* Handle */
.mydiv::-webkit-scrollbar-thumb {
background: red;
border-radius: 10px;
}
    

/* Handle on hover */
.mydiv::-webkit-scrollbar-thumb:hover {
background: #b30000;

</style>

对于使用sass的人来说，这里是一个具有基本功能(拇指，轨道颜色和宽度)的mixin。我没有广泛地测试它，所以请随意指出任何错误。

@mixin element-scrollbar($thumb-color, $background-color: mix($thumb-color, white,  50%), $width: 1rem) {
// For Webkit
&::-webkit-scrollbar-thumb {

}


&::-webkit-scrollbar-track {

&::-webkit-scrollbar {
width: $width;
height: $width;
}


// For Internet Explorer
& {
scrollbar-face-color: $thumb-color;
scrollbar-arrow-color: $thumb-color;
scrollbar-track-color: $background-color;
}


// For Firefox future compatibility
// This is W3C draft and does not work yet. Use html-firefox-scrollbar mixin instead.
& {
scrollbar-color: $thumb-color $background-color;
scrollbar-width: $width;
}
}


// For Firefox
@mixin html-firefox-scrollbar($thumb-color, $background-color: mix($thumb-color, white,  50%), $firefox-width: this) {
// This must be used on html/:root element to take effect
