How to use CSS to achieve line breaks (three methods)

Line wrapping refers to the behavior of automatically moving to the next line when text or other content reaches the end of the line. In web design, correct line breaks can make the page look more comfortable and natural. In CSS, achieving correct line breaks requires understanding some principles and techniques. This article will introduce you to several methods on how to use CSS to achieve line breaks.

Method 1: Use word-wrap

In CSS3, the word-wrap attribute is provided, which can be used to control the way text is wrapped. This attribute has the following values:

• normal: the default attribute value, which means that the text is not restricted and can exceed the boundary;
• break-word: means when the text exceeds the boundary , automatically truncate the word and wrap it, but if the word itself is very long, it will still exceed the boundary;
• anywhere: means that the text can wrap anywhere;
• overflow-wrap: means that the text can wrap anywhere Wrap around "word" and truncate newlines if a long word is encountered.

Using word-wrap is also very simple. You only need to set the corresponding attributes in CSS. For example:

p {
  word-wrap: break-word;
}

The above code will cause the text in the p element to be automatically truncated when it encounters a boundary and wrapped according to the length of the word.

Method 2: Using word-break

Word-wrap is not always the ideal solution because sometimes you want to avoid truncating a word and instead want it to wrap anywhere. In this case we can use word-break attribute.

The word-break attribute has the following values:

• normal: The default attribute value means that the text is restricted and truncation in the middle of the word is not allowed.
• break-all: Indicates a line break at any position, even in the middle of a word. However, it will destroy the integrity of the word and is not recommended.
• keep-all: Indicates that the text is only broken at spaces or hyphens, suitable for Asian languages ​​and other languages ​​that do not use spaces.

For example, if you want to break a complete Chinese character in the text line break, you can use the following code:

p {
  word-break: break-all;
}

Method 3: Use white-space

white-space is a CSS property used to control spaces and line breaks in text. It has the following values:

• normal: the default attribute value, which means that multiple spaces and line breaks in the text will be merged into one space;
• pre: means that there are multiple spaces in the text Spaces and line breaks will be retained and will not be merged;
• nowrap: indicates that the text will not be automatically wrapped.
• pre-wrap: Indicates that multiple spaces and line breaks in the text will be retained, but lines will be automatically wrapped and no horizontal scroll bars will appear.
• pre-line: Indicates that multiple spaces in the text will be merged into one space, but line breaks will be retained, automatic line wrapping, and no horizontal scroll bar will appear.

For example, in several lines of code comments, if you want to retain the original spaces and line breaks, you can use the following code:

.comment {
  white-space: pre;
}

This can ensure that the text is on the page The displayed format is consistent with the format in the original code.
