How to set scroll bar width in css

CSS (Cascading Style Sheets) is an essential technology in web design and development. It can control the appearance and layout of web pages through style sheets. The scroll bar is an interactive element that we often encounter when browsing the web every day. We can control the color, size and position of the scroll bar through CSS. This article will focus on how to set the scroll bar width.

In CSS, we can use the ::-webkit-scrollbar pseudo-element to control the style and properties of the scroll bar. Among them, -webkit- is a private prefix for browsers that support the WebKit browser kernel. However, most major browsers now support this pseudo element, so we can use it directly.

To set the width of the scroll bar, we need to specify the width attribute of ::-webkit-scrollbar-thumb. This property controls the width of the slider on the scroll bar.

As an example, in CSS, we can write like this:

::-webkit-scrollbar {
    width: 20px;
}

::-webkit-scrollbar-thumb {
    width: 10px;
    background-color: #ccc;
}

In this example, we set the overall width of the scroll bar to 20 pixels and the width of the slider to 10 pixels , the color is gray. In this way, we can easily control the width of the scroll bar.

Of course, in addition to width, there are many other settings for scroll bar styles and properties. For example, we can use ::-webkit-scrollbar-track to control the style and properties of the scroll bar track, use ::-webkit-scrollbar-button to control the style and properties of the button, and use ::-webkit-scrollbar-corner to Control the styles and properties of scroll bar corners and more.

In short, CSS provides a lot of flexibility, and we can achieve a variety of effects through it. If you want to have a deeper understanding of CSS-related knowledge, you can refer to some excellent learning materials, such as "The Definitive Guide to CSS".
