添加 CSS 模块样式表

注意:react-scripts@2.0.0 及更高版本提供此功能。

¥Note: this feature is available with react-scripts@2.0.0 and higher.

该项目支持 CSS 模块 以及使用 [name].module.css 文件命名约定的常规样式表。CSS 模块允许通过自动创建格式为 [filename]\_[classname]\_\_[hash] 的唯一类名来限定 CSS 的范围。

¥This project supports CSS Modules alongside regular stylesheets using the [name].module.css file naming convention. CSS Modules allows the scoping of CSS by automatically creating a unique classname of the format [filename]\_[classname]\_\_[hash].

提示:如果你想使用 Sass 预处理样式表,请确保 按照安装说明进行操作,然后更改样式表文件扩展名,如下所示:[name].module.scss[name].module.sass

¥Tip: Should you want to preprocess a stylesheet with Sass then make sure to follow the installation instructions and then change the stylesheet file extension as follows: [name].module.scss or [name].module.sass.

CSS 模块让你可以在不同的文件中使用相同的 CSS 类名,而不必担心命名冲突。此处 了解有关 CSS 模块的更多信息。

¥CSS Modules let you use the same CSS class name in different files without worrying about naming clashes. Learn more about CSS Modules here.

Button.module.css

.error {
background-color: red;
}

another-stylesheet.css

.error {
color: red;
}

Button.js

import React, { Component } from 'react';
import styles from './Button.module.css'; // Import css modules stylesheet as styles
import './another-stylesheet.css'; // Import regular stylesheet

class Button extends Component {
render() {
// reference as a js object
return <button className={styles.error}>Error Button</button>;
}
}

结果

¥Result

与其他 .error 类名称没有冲突

¥No clashes from other .error class names

<!-- This button has red background but not red text -->
<button class="Button_error_ax7yz">Error Button</button>

这是一项可选功能。完全支持常规 <link> 样式表和 CSS 文件。CSS 模块打开为以 .module.css 扩展名结尾的文件。

¥This is an optional feature. Regular <link> stylesheets and CSS files are fully supported. CSS Modules are turned on for files ending with the .module.css extension.
