Summarize some methods of setting line breaks in CSS

CSS is an important language in web design. It is used to control the layout, typesetting and style of web pages. Among them, controlling the style of text is also one of the important functions of CSS. In articles, how to use CSS to control text wrapping is also very important. This article will introduce some methods of setting line breaks in CSS.

1. Use the word-break attribute

There is a word-break attribute in CSS, which can control the way text is wrapped. When there are long words or URLs in the text content, without any control, these words will span multiple lines of text, affecting the aesthetics of the entire text. At this point, you can use the word-break attribute to control the way these long words are wrapped. Common attribute values ​​​​of the word-break attribute are as follows:

break-all: Indicates line breaks within words;

keep-all: Indicates line breaks only between words, not within words. ;

normal: Indicates that the default line breaking method is used, and the line breaks in the middle of the word.

For example, the following code can break-all a long word or URL:

p {
  word-break: break-all;
}

2. Use the word-wrap attribute

The word-wrap attribute is also A CSS property that controls text wrapping.

By default, when the width of the text exceeds the width of the container, the text will not wrap, but a horizontal scroll bar will appear. Therefore, when the text width exceeds the container width, we need to achieve automatic line wrapping by setting the word-wrap attribute.

The word-wrap attribute generally has two common values:

normal: indicates line wrapping in the default way, that is, only breaking between words, not within words.

break-word: Indicates that the text will be broken within the word. If a word is too long, it will be broken within the word.

For example, the following code can automatically wrap text using break-word:

p {
  word-wrap: break-word;
}

3. Use the white-space attribute

The white-space attribute can also be used Used to control the way text is wrapped.

By default, the default value of the white-space attribute is normal, which means that the text will not wrap and will only be separated at spaces. And when we set the attribute value of white-space to pre-wrap, we can achieve the effect of automatic line wrapping at a specific position.

For example, the following code can automatically wrap text using the pre-wrap attribute:

p {
  white-space: pre-wrap;
}

The above are three commonly used CSS methods to set line wrapping. In the actual web design process, selection based on factors such as text length and layout can better improve the user experience and visual effects of the web page.
