Detailed explanation of CSS text trimming properties: text-overflow and overflow

In web design, text is one of the important components of page content. When the text content is too long, it often appears that the display is incomplete. In this case, you need to use the text trimming attribute to deal with it. In CSS, commonly used text trimming properties include text-overflow and overflow. This article will introduce the usage and effects of these two properties in detail and provide specific code examples.

1. text-overflow: Text overflow handling

The text-overflow property is used to control how text content that exceeds the container is displayed. Commonly used attribute values ​​are:

• clip: The default value means that the text content beyond the container will not be displayed and will be cropped directly.
• ellipsis: When the text content exceeds the container, an ellipse is displayed to indicate the truncation of the text.
• string: Custom string. When the text content exceeds the container, the specified string is displayed to represent the truncation of the text.

Code example:

.container {
  width: 200px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

In the above example, first set the width of a container to 200px, and then set the white-space attribute to nowrap, which ensures that the text does not wrap. Then use overflow: hidden to hide the overflow part, and finally use text-overflow: ellipsis to display the ellipsis. When the text content exceeds the width of the container, ellipses will automatically appear to indicate truncation of the text.

2. overflow: Container overflow processing

The overflow property is used to control the display mode when the content in the container overflows. Commonly used attribute values ​​are:

• visible: the default value, indicating that the container content is displayed outside the container when it overflows.
• hidden: Indicates hiding overflow content.
• scroll: Indicates that the scroll bar is displayed to view the overflowing content.
• auto: Indicates that if the content overflows, the scroll bar will be displayed; otherwise, it will not be displayed.

Code example:

.container {
  width: 200px;
  height: 200px;
  overflow: hidden;
}

In the above example, set the width and height of a container to 200px respectively, and then use overflow: hidden to hide the overflow content. When the content in the container exceeds the width or height of the container, it will be hidden.

To sum up, text-overflow and overflow are two commonly used CSS properties, which are used to handle the truncation of text content and the display mode when the container overflows. They can help us better control the display of text and containers and improve the quality of web design. In practical applications, these attributes can be flexibly used according to needs to achieve the desired effects.
