How to remove scroll bar in css

CSS is a style sheet language for web pages, used to control the layout and display effects of web pages. One of the more annoying problems is the display of scroll bars. Especially in some beautifully designed web pages, scroll bars will obviously affect the beauty of the overall layout. So today I will introduce how to remove the scroll bar.

1. Use the overflow attribute to remove the scroll bar

We know that when the text or pictures in a container exceeds the size of the containing container, a scroll bar will appear. We can control whether scroll bars appear through the overflow property in CSS.

For example, when we set the overflow attribute to hidden, the excess part of the container will be hidden, and no scroll bar will appear. The code is as follows:

.container{
  width: 400px;
  height: 300px;
  overflow: hidden;
}

This method can effectively remove the scroll bar, but it also means that the user will not be able to view content that exceeds the container size. Therefore, attention needs to be paid in actual use.

2. Use Webkit features to remove scroll bars

Webkit is a browser engine, and the properties and values ​​supported by its style sheet language are somewhat different from standard CSS. We can use the features of Webkit to remove the scroll bar, such as using the ::-webkit-scrollbar pseudo-class.

The code is as follows:

.container::-webkit-scrollbar {
  width: 0px;
  height: 0px;
}

It should be noted in this implementation method that Webkit is a private CSS property and can only take effect when using a browser based on the Webkit engine. If the user uses another browser, they will most likely see scroll bars.

3. Combine the two methods to remove the scroll bar

We can combine the first two methods to take into account their respective advantages and disadvantages. For example, we can use the overflow attribute to hide content that exceeds the container size, and use Webkit features to remove scroll bars to ensure that users can view all content without being affected by scroll bars.

The code is as follows:

.container{
  width: 400px;
  height: 300px;
  overflow: hidden;
}

.container::-webkit-scrollbar {
  width: 0px;
  height: 0px;
}

Through the above method, we can achieve the effect of removing the scroll bar. However, it should be noted that in actual use, the choice should be based on specific circumstances. If the content will not exceed the container size, you can directly remove the scroll bar; if you need to display the excess content, you can use a combination of the two methods. At the same time, the user's browser type needs to be considered to ensure compatibility and usability.
