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>
      <div id="tutorial">
         <img src="https://www.tutorialspoint.com/about/images/about-mini-logo.jpg">
         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.
      </div>
   </body>
</html>

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。

<!DOCTYPE html>
<html>
   <body>
      <style>
         .visible-scrollbar,
         .mostly-customized-scrollbar {
            display: block;
            width: 300px;
            overflow: auto;
            height: 150px;
         }
         .invisible-scrollbar::-webkit-scrollbar {
            display: none;
         }
         .mostly-customized-scrollbar::-webkit-scrollbar {
            width: 300px;
            height: 8px;
            background-color:#7D3C98 ;
         }
         .mostly-customized-scrollbar::-webkit-scrollbar-thumb {
            outline: 1px solid #FBFCFC;
         }
      </style>
      <div class="visible-scrollbar">
