How to wrap the excess part in css

CSS line wrapping is a common web page layout technique. It can make the text content in the web page automatically wrap when it exceeds the width of the container under the limit of the container width, ensuring the overall beauty and readability of the web page. Here’s a closer look at this technique.

1. What is CSS excess line break?

In web design, we often encounter a problem: the width of the container is limited, but how to deal with the text content exceeding the width of the container. To solve this problem, CSS provides functionality beyond partial line breaks.

Specifically, when the container width is limited, if the text content exceeds the container width, CSS will automatically wrap the text content. In this way, while ensuring the width of the container, the text can be displayed more completely and the page beauty and readability can be enhanced.

2. Implementation of excess line breaks in CSS

There are generally two ways to implement excess line breaks in CSS: using the word-wrap attribute and using the overflow-wrap attribute.

1. word-wrap attribute

The word-wrap attribute can automatically wrap long words and URL addresses. It has two values: normal and break-word.

· normal: default value. Indicates that only line breaks are performed between words, and a word is not split into multiple lines.

· break-word: Indicates line breaking within a word. If a word exceeds the width of the container, the word can be split into multiple lines.

The following is a sample code:

.container {
    width: 300px;
    height: 100px;
    border: 1px solid #555;
    word-wrap: break-word;
}

In the above code, a container with a width of 300 pixels and a height of 100 pixels is defined, and a 1-pixel-wide black border is set . At the same time, use the word-wrap attribute to automatically wrap the text content beyond the text. When the text content exceeds the width of the container, it will automatically wrap.

2. overflow-wrap attribute

The overflow-wrap attribute can also realize automatic line wrapping of text. It has two values: normal and break-word.

· normal: default value. Same as the normal value of word-wrap, it only breaks lines between words and does not split a word into multiple lines.

· break-word: The same as the break-word value of word-wrap, indicating a line break within the word. If a word exceeds the width of the container, the word can be split into multiple lines.

The following is a sample code:

.container {
    width: 300px;
    height: 100px;
    border: 1px solid #555;
    overflow-wrap: break-word;
}

In the above code, a container with a width of 300 pixels and a height of 100 pixels is also defined, and a 1-pixel-wide black color is set. frame. At the same time, use the overflow-wrap attribute to automatically wrap the text content beyond the text. When the text content exceeds the width of the container, it will also wrap automatically.
