法學如何在移動裝置上使自定義捲軸箭頭生效？
您可能已經注意到，一些網站具有獨特的捲軸，賦予它們獨特的感覺和外觀，因為自定義捲軸正變得越來越普遍。自定義捲軸可以通過幾種不同的方式實現。本文將使用最簡單的方法，即 CSS。
我們在應用程式中使用 CSS 來增強網頁的視覺吸引力。使用 CSS，我們現在可以更改捲軸的外觀。讓我們看看如何在移動裝置上使自定義捲軸箭頭生效。
在移動裝置上使自定義捲軸箭頭生效
過去，可以使用非標準 CSS 屬性（如 `scrollbar-base-color`）修改網站上的捲軸，您可以將其應用於滾動元素（如 `
`），並實現非常酷炫的效果。IE 放棄了這種方法。
如今，自定義捲軸再次可用，儘管這次使用了 WebKit。這些屬性現在使用“Shadow DOM”並且帶有廠商字首（例如：`-webkit-scrollbar`）。這已經存在一段時間了。
為了更深入地瞭解如何在移動裝置上使自定義捲軸箭頭生效，讓我們來看以下示例。
示例
在下面的示例中，我們使用 `webkit-scrollbar` 使捲軸在移動裝置上生效，並向捲軸應用 CSS。
<!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.

當指令碼執行時，它將生成一個輸出，其中包含影像、一些文字和網頁上的可滾動顯示。
示例
考慮以下示例，我們使用 `webkit-scrollable` 使內容在網頁上以及箭頭一起滾動。
<!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">

World Twenty20, the 2011 Cricket World Cup, and the 2013 ICC Champions
Trophy, the most by any captain. He also led India to victory in the 2010
and 2016 Asia Cup.

執行上述指令碼後，將彈出輸出視窗，顯示文字以及在網頁上顯示的可滾動箭頭。
示例
執行以下程式碼，觀察我們將如何使用 `webkit-scrollable` 建立自定義可滾動區域。
<!DOCTYPE html>

<style>
body {
font-size: 15pt;
}
::-webkit-scrollbar {

::-webkit-scrollbar-button:single-button {
background-color: fuchsia;
height: 10px;
width: 10px;
}
::-webkit-scrollbar-thumb {
background: maroon;
}
::-webkit-scrollbar-track {
background: silver;

<p>In the 1930s and 1940s, Ducati manufactured radios, cameras, and
electrical products such as razors. Ducati also made a marine binocular called the BIMAR for the Kriegsmarine during World War II, some of which
were sold on the civilian market after the war.The Ducati Sogno was
a half-frame Leica-like camera which is now a collector's item.</p>
