How to set no line break style in css

css (Cascading Style Sheets) is a style language used to describe how web pages (HTML documents) are rendered. It allows us to control the appearance and layout of elements such as color, font, size, and position in HTML documents by setting styles.

Sometimes, we may want to avoid line breaks in certain places in the web page and keep it displayed on the same line. At this time, we can use CSS to set no line breaks.

There are many ways to set non-line wrapping in CSS. Below we will introduce two commonly used methods.

1. Use the white-space attribute

The white-space attribute is used to set the processing method of whitespace (spaces, line breaks, etc.) inside the element. By default, the value of the white-space attribute is normal, that is, when there are consecutive whitespace characters, they will be merged into one space, and when a newline character is encountered, the line will be automatically wrapped.

If you want to prevent the content inside the element from wrapping, you can set the value of the white-space attribute to nowrap. The sample code is as follows:

<style>
    .nowrap {
        white-space: nowrap;
    }
</style>
<div class="nowrap">这是一段不换行的文本，当文本过长时不会自动换行。</div>

2. Use CSS pseudo-elements::before and ::after

CSS pseudo-elements::before and ::after can be in front of an element Or insert a piece of content later. Using this feature, we can insert a blank element so that the content will not wrap automatically.

Specifically, we can insert an empty inline block element by setting the content attribute of ::before or ::after to an empty string, and then setting the display attribute to inline-block or inline. Or inline elements to achieve the effect of no line breaks. The sample code is as follows:

<style>
    .nowrap {
        white-space: nowrap;
    }
    .no-wrap::before,
    .no-wrap::after {
        content: "";
        display: inline-block;
    }
</style>
<div class="no-wrap">这是一段不换行的文本，当文本过长时不会自动换行。</div>

The above are two commonly used CSS methods to set no line breaks. It should be noted that the effect of no line wrapping is only effective within the current element. If you want to prevent the entire web page from automatically wrapping, you need to apply the setting to the body element.
