What to do if css content does not wrap?

CSS is an important part of web design. It can add various styles to web pages, such as colors, fonts, layouts, etc. Among them, content line wrapping is also an important style in CSS. When we need to adjust the text layout on the page, content line wrapping is particularly important.

In CSS, browsers use properties to control the automatic wrapping of text. By default, text wraps according to their container, which is determined by the browser's word-wrapping mechanism. But sometimes, we want the text to not wrap in the container. In this case, we can use the following methods to achieve this.

1. Use the white-space attribute

The white-space attribute can control how text spaces and line breaks are displayed.

The white-space attribute has four values, namely normal, nowrap, pre, and pre-wrap. Among them, normal is the default value. nowrap means that the text will not automatically wrap when it overflows the container, pre means that line breaks will be retained in the text, but the text will not wrap automatically at the edge of the container, and pre-wrap means that if the text has line breaks at the edge of the container, then it should be Line break.

The sample code is as follows:

div {
  width: 200px;
  height: 100px;
  white-space: nowrap;
}

The above code will prevent all text in a div element with a width of 200px and a height of 100px from wrapping automatically. If we change the white-space attribute to pre, then newlines appearing in the text will be preserved. If pre-wrap, the text can have line breaks at the edge of the container.

2. Use the text-overflow attribute

The text-overflow attribute is used to replace the overflow content with the specified characters when the text overflows the container.

The text-overflow attribute has three values, namely clip, ellipsis, and string. Among them, clip is the default value, which means that when the text overflows the container, the text will be hidden; ellipsis means that the ellipsis is displayed at the overflowed text; string means that the specified character is displayed at the text instead of the ellipsis.

The sample code is as follows:

div {
  width: 200px;
  height: 100px;
  text-overflow: ellipsis;
  overflow: hidden;
  white-space: nowrap;
}

The above code will replace the text in a div element with a width of 200px and a height of 100px with an ellipsis when it overflows.

3. Use the word-break attribute

The word-break attribute can control how words are broken and wrapped.

The word-break attribute has three values, namely normal, break-all, and keep-all. Among them, normal is the default value, which means that the browser can break a word anywhere; break-all means breaking lines within the word; keep-all means preventing line breaks on characters such as Chinese or Japanese.

The sample code is as follows:

div {
  width: 200px;
  height: 100px;
  word-break: keep-all;  
}

The above code will not wrap the Chinese or Japanese characters in the text in a div element with a width of 200px and a height of 100px.

In short, to achieve non-breaking content in CSS, we can use white-space, text-overflow, word-break and other attributes to achieve this. Using these attributes can enhance the readability and aesthetics of web pages and improve the user experience.
