要使用CSS创建自定义滚动条，代码如下-
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<style>
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
height: 200vh; /*to create a scrollbar*/
}
::-webkit-scrollbar {
width: 20px;
}
p {
font-size: 40px;
}
::-webkit-scrollbar-track {
box-shadow: inset 0 0 5px grey;
border-radius: 10px;
}
::-webkit-scrollbar-thumb {
background: rgb(75, 22, 161);
border-radius: 2px;
}
::-webkit-scrollbar-thumb:hover {
background: #9156ff;
}
</style>
</head>
<body>
