您可能已经注意到具有独特滚动条的网站，这些网站赋予它们独特的感觉和外观，因为自定义滚动条变得越来越普遍。自定义滚动条可以通过几种不同的方式简单地实现。本文将使用最简单的方法，即 CSS。
我们使用 CSS 来增强应用程序中网页的视觉吸引力。使用 CSS，我们现在可以更改滚动条的外观。让我们看看如何使滚动条自定义箭头在移动设备上工作。
使滚动条自定义箭头在移动设备上工作
过去，网站上的滚动条可以使用非标准 CSS 属性（如scrollbar-base-color）进行修改，您可以将其应用于滚动的元素（如 ）并做一些非常棒的事情。 IE 放弃了这一点。
自定义滚动条今天再次可用，尽管这次使用了 WebKit。这些属性现在使用“Shadow DOM”并且带有供应商前缀（例如：-webkit-scrollbar）。这已经存在了一段时间了。
为了获得有关使滚动条自定义箭头在移动设备上工作的更多想法，让我们看看以下示例。
示例
在下面的示例中，我们使用 webkit-scrollbar 使滚动条在移动设备上工作并将 CSS 应用于滚动条。
<!DOCTYPE html>
<html>
<body>
<style>
div{
max-width:400px;
max-height:250px;
overflow-y: scroll;
overflow-x: hidden;
}
div::-webkit-scrollbar {
width: 0.5em;
}
div::-webkit-scrollbar-track {
-webkit-box-shadow: inset 0 0 2px rgba(1,1,1,0.4);
}
div::-webkit-scrollbar-thumb {
background-color: #D5F5E3;
outline: 1px solid #FBFCFC;
}
</style>

Tutorials Point originated from the idea that there exists a class of readers
who respond better to online content and prefer to learn new skills at their
own pace from the comforts of their drawing rooms.The journey commenced with
a single tutorial on HTML in 2006 and elated by the response it generated, we
worked our way to adding fresh tutorials to our repository which now proudly
flaunts a wealth of tutorials and allied articles on topics ranging from programming
languages to web designing to academics and much more.

当脚本执行时，它将生成一个由图像、一些文本和网页上可滚动显示组成的输出。
示例
考虑以下示例，我们使用 webkit-scrollable 使内容在网页上随着箭头滚动。

<style>
.visible-scrollbar,
.mostly-customized-scrollbar {
display: block;
width: 300px;
