CSS text overflow attribute optimization tips: text-overflow and white-space

CSS is one of the most commonly used style languages in front-end development, and the text overflow problem is A challenge we often encounter. Text overflow occurs when the text content exceeds the given container size. To solve this problem, CSS provides several properties and techniques, including text-overflow and white-space. This article will introduce how to use these two properties and provide specific code examples.

1. Text-overflow attribute

The text-overflow attribute is used to define the processing method when text overflows. It has the following optional values:

1. clip: directly clip the text without displaying the overflow part.
2. ellipsis: Display ellipses in overflow parts.
3. custom: User-defined display method of overflow part.

The following is a simple example that demonstrates the effect of text-overflow: ellipsis:

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

 This is a very long text that will be truncated. 

In the above code, by setting the width of the container to 200px, and setting white- space is nowrap and overflow is hidden, so that when the text exceeds the width of the container, the overflow is hidden and an ellipsis is displayed at the end.

2. White-space attribute

The white-space attribute is used to control how text line breaks and whitespace characters are processed. Commonly used values include the following:

1. normal: Default value, text will wrap automatically, and consecutive whitespace characters will be merged into one space.
2. nowrap: Force the text not to wrap, regardless of the container width, and continuous whitespace characters will be merged into one space.
3. pre: Preserve newlines and whitespace characters in the source code without automatic line wrapping.
4. pre-wrap: Preserve newlines and whitespace characters in the source code, but allow text to wrap automatically.
5. pre-line: Merges consecutive whitespace characters, but retains line breaks in the source code, allowing text to wrap automatically.

The following is an example showing the effect of white-space: nowrap:

.container { width: 200px; white-space: nowrap; }

 This is a very long text that will not wrap. 

In the above code, set white-space to nowrap so that the text does not wrap automatically. Even if the text content exceeds the width of the container, it will not wrap.

3. Comprehensive application example

The following is an example of comprehensive application of text-overflow and white-space:

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

 This is a very long text that will be truncated with ellipsis. 

In the above code, by setting white-space to nowrap causes the text to not wrap automatically. By setting overflow to hidden and text-overflow to ellipsis, the portion of text that exceeds the width of the container will be hidden and an ellipsis will be displayed at the end.

In actual development, it can be adjusted and expanded according to specific needs, such as customizing the display method of the overflow part, changing the ellipsis style, etc.

To sum up, text-overflow and white-space are common attributes and techniques to solve text overflow problems. By using them flexibly, we can achieve better text display effects and improve user experience.

(Note: The style code in the above example is only for demonstration effect. Please adjust the style according to specific needs in actual projects)
