How to achieve no line breaks in css

CSS is a style sheet language commonly used in front-end development, used to set the layout, font, color, size and other styles of web pages. When writing CSS styles, we often encounter some long sentences or long codes that require line breaks. But sometimes we don't want to wrap lines and want them to remain displayed on one line. This article will introduce how to achieve no line breaks in CSS code.

1. Why does the code automatically wrap?

Let’s first understand the reason why the code automatically wraps. In the code, if the attribute value of an element is too long and the display is incomplete, most browsers will automatically wrap the text by default. The purpose of this is to facilitate reading and maintenance and ensure the readability of the code.

For example, the following is a CSS code:

.container {
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  background-color: #fff;
  border: 1px solid #ccc;
  box-shadow: 1px 1px 1px #eee;
}

If one of the attribute values ​​​​is too long and exceeds the visible area of ​​​​the editor or browser, it will automatically wrap and become The following code:

.container {
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  background-color: #fff;
  border: 1px solid #ccc;
  box-shadow: 1px 1px 1px #eee;
}

Although this is more readable, we need to use some special techniques to deal with certain situations where we need to save space or force no line breaks.

2. Solution to CSS code not wrapping

There are many techniques for CSS code not wrapping. Here are some commonly used methods:

1. Use white- space attribute

In CSS, we can use the white-space attribute to set the wrapping method of text. This attribute has three values: normal (default value), pre-line and nowrap.

• normal: Browser default behavior, automatically adjusted according to spaces and newlines.
• pre-line: Line breaks according to the real line breaks in the text.
• nowrap: No line wrapping.

Therefore, if we want to force no line breaks in the code, we can set the white-space attribute to nowrap in the style sheet.

For example, the following code can prevent the text content from wrapping and keeping it on one line. It overrides the default wrapping settings, leaving the text content in its original position.

.text {
  white-space: nowrap;
}

2. Use the word-break attribute

The word-break attribute in CSS is used to specify the method of automatic line wrapping. This attribute has 4 values: normal (default value), break-all, keep-all and break-word.

• normal: Automatically wrap lines based on spaces and hyphens.
• break-all: When a word is too long and exceeds the boundary of the container, automatically wrap to the next line.
• keep-all: Avoid wrapping within a word and put the entire word in a narrow container.
• break-word: Similar to break-all, but in some specific cases will keep the entire word on the same line.

Therefore, if we want to force no line breaks in the code, we can set the word-break attribute to keep-all in the style sheet.

For example, the following code can prevent the text content from wrapping and keeping it on one line. It overrides the default wrapping settings, keeping text content in its original position.

.text {
  word-break: keep-all;
}

3. Use the text-overflow attribute

The text-overflow attribute in CSS is used to specify how the portion beyond the text container is displayed. This property has 2 values: clip (default value) and ellipsis.

• clip: clip the text, and the excess part will be hidden.
• ellipsis: Use ellipses to replace excess parts.

Therefore, if we want to force no line breaks in the code and display ellipsis in the excess part, we can set the text-overflow attribute to ellipsis in the style sheet.

For example, the following code can prevent the text content from wrapping, keep it on one line, and display ellipsis in the excess part. It overrides the default wrapping settings, keeping text content in its original position.

.text {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

4. Use the nowrap attribute

In order to ensure that elements do not wrap, there is also an attribute in CSS similar to the white-space attribute, called the nowrap attribute. This attribute has only one value: nowrap, which means that elements are prohibited from wrapping.

For example, the following code can prevent the text content from wrapping and keeping it on one line. It overrides the default wrapping settings, keeping text content in its original position.

.text {
  white-space: nowrap;
}

5. Use the inline-block attribute

In CSS, we can also use the display:inline-block attribute to maintain the display mode of the element. This attribute allows elements to be displayed on the same line without wrapping.

For example, the following code can prevent the text content from wrapping and keeping it on one line. It overrides the default wrapping settings, keeping text content in its original position.

.text {
  display: inline-block;
}

6. Use the height attribute

In CSS, we can also use the height attribute to specify the height of the container. If the height of an element is defined as a certain value, then its content cannot wrap automatically.

For example, the following code can prevent the text content from wrapping and keeping it on one line. It will force the height of the container to 20px, keeping the text content in its original position.

.text {
  height: 20px;
}

3. Summary

Whether we are considering saving space or for other reasons, sometimes we may need to force no line breaks in CSS. This article introduces 6 commonly used techniques, including white-space attribute, word-break attribute, text-overflow attribute, nowrap attribute, inline-block attribute and height attribute. Choosing appropriate attributes and values ​​depends on the specific application scenario and requirements.

Although these methods essentially prohibit elements from automatically wrapping, the applicable scenarios and implementation methods of each method are different. Mastering these techniques can help us better manage CSS style sheets and improve the readability and maintainability of the code.
