CSS scrollbar-width用法及代码示例

scrollbar-width属性用于设置显示时元素滚动条的宽度或厚度。此属性可用于以下页面上：用户接口要求元素应更突出地显示，并且缩小滚动条宽度可为元素提供更多空间。

这目前是实验性质，某些主要的浏览器可能不受支持。

用法:

scrollbar-width:auto | thin | none | initial | inherit

属性值：

auto:它用于设置滚动条宽度，以由浏览器自动设置。它是默认值。

例：

<!DOCTYPE html> 
<html> 
      
<head> 
    <title>CSS | scrollbar-width property</title> 
      
    <style> 
        .scrollbar-auto { 
            scrollbar-width:auto; 
            background-color:lightgreen; 
            height:150px; 
            width:200px; 
            overflow-y:scroll; 
        } 
    </style> 
</head> 
  
<body> 
    <h1 style="color:green"> 
        GeeksforGeeks 
    </h1> 
      
    <b>CSS | scrollbar-width</b> 
      
    <p>scrollbar-width:auto</p> 
      
    <div class="scrollbar-auto"> 
        GeeksforGeeks is a computer science 
        portal with a huge variety of well 
        written and explained computer science 
        and programming articles, quizzes and 
        interview questions. The portal also  
        has dedicated GATE preparation and 
        competitive programming sections.
