CSS Display Scrollbar

In web development, sometimes we need to display a lot of content but don’t want the page to appear too crowded. In this case, we can use CSS to display scrollbars, allowing users to easily view content. This article will detail how to use CSS to display scrollbars, including styling horizontal and vertical scrollbars.

Vertical Scrollbar

First, let’s look at how to display a vertical scrollbar on a web page. Typically, when content exceeds the height of its container, the browser automatically displays a vertical scrollbar, but we can also customize the scrollbar’s style using CSS.

/* Set the container's height and width */ 
.container { 
height: 300px; /* container height */ 
width: 200px; /* container width */ 
overflow-y: scroll; /* display vertical scrollbar */ 
} 

/* set the content's height */ 
.content { 
height: 500px; /* content's height exceeds the container's height */ 
}

In the above code, we set a fixed height and width for the container. When the content’s height exceeds the container’s height, a vertical scrollbar automatically appears. Using the overflow-y: scroll; property, we can control the display of the vertical scrollbar. We also need to set the content’s height to ensure that the content exceeds the container’s height.

Horizontal Scrollbar

In addition to the vertical scrollbar, we may also need to display a horizontal scrollbar in some cases to accommodate content that extends horizontally beyond the container. The following code example demonstrates how to display a horizontal scrollbar.

/* Set the height and width of the container */
.container {
height: 200px; /* Container height */
width: 300px; /* Container width */
overflow-x: scroll; /* Display horizontal scrollbar */
}

/* Set the width of the content */
.content {
width: 500px; /* Content width exceeds container width */
}

In the above code, we set a fixed height and width for the container. When the content width exceeds the container width, a horizontal scrollbar automatically appears. Using the overflow-x: scroll; property, we can control the display of the horizontal scrollbar. Similarly, we need to set the content width to ensure that the content exceeds the container width.

Showing Vertical and Horizontal Scrollbars Simultaneously

Sometimes, we need to display both vertical and horizontal scrollbars simultaneously to display overly long content. Below is a sample code showing how to display both vertical and horizontal scrollbars simultaneously.

/* Set the height and width of the container */
.container {
height: 200px; /* Container height */
width: 300px; /* Container width */
overflow: scroll; /* Display vertical and horizontal scrollbars */
}

/* Set the height and width of the content */
.content {
height: 500px; /* Content height exceeds container height */
width: 500px; /* Content width exceeds container width */
}

In the above code, we set a fixed height and width for the container. When the content’s height or width exceeds the container’s height or width, a vertical or horizontal scrollbar automatically appears. Using the overflow: scroll; property, we can control the display of both vertical and horizontal scrollbars. We also need to set the content’s height and width to ensure that the content exceeds the container’s height and width.

Through the above introduction, we’ve seen how to use CSS to display vertical, horizontal, and simultaneous scrollbars. By properly setting the height and width of the container and controlling the height and width of the content, we can achieve customized scrollbar display, making it easier for users to view large amounts of content.
