react 集成 tailwindcss

已创建的项目集成 tailwindcss

1.安装依赖

npm install tailwindcss

2. 根目录下创建文件tailwind.config.js  初始化文件

// https://unpkg.com/browse/tailwindcss@3.1.6/stubs/defaultConfig.stub.js
 
/** @type {import('tailwindcss').Config} */
export default {
  purge: ['./src/**/*.{js,ts,tsx,jsx}'],
  corePlugins: {
    preflight: false,
    container: false
  },
  theme: {
    spacing: () => {
      let baseObj = {
        120: '120px',
        130: '130px',
        140: '140px',
        160: '160px',
        180: '180px',
        200: '200px',
        '1/2': '50%',
        '1/3': '33.333333%',
        '2/3': '66.666667%',
        '1/4': '25%',
        '3/4': '75%',
        '1/5': '20%',
        '2/5': '40%',
        '3/5': '60%',
        '4/5': '80%',
        '1/6': '16.666667%',
        '5/6': '83.333333%',
        '1/12': '8.333333%',
        '5/12': '41.666667%',
        '7/12': '58.333333%',
        '11/12': '91.666667%',
        full: '100%'
        // auto: 'auto',
      }
 
      // 0-100 px
      let obj = {}
      for (let i = 0; i <= 100; i++) {
        obj[i] = `${i}px`
      }
 
      return {
        ...obj,
        ...baseObj
      }
    },
    fontSize: theme => theme('spacing'),
    borderRadius: theme => theme('spacing'),
    borderWidth: theme => theme('spacing'),
    // lineHeight: (theme) => theme('spacing'),
 
    width: theme => ({
      ...theme('spacing'),
      'max-content': 'max-content',
      screen: '100vw'
    }),
    maxWidth: theme => theme('width'),
    minWidth: theme => theme('width'),
    height: theme => ({
      ...theme('width'),
      screen: '100vh'
    }),
    maxHeight: theme => theme('height'),
    minHeight: theme => theme('height')
  }
}

3. 在全局css  index.css 文件中 导入Tailwindcss

@import './_preflight'; // 这是做样式覆盖的 ，可不写
 
@tailwind base;
@tailwind components;
@tailwind utilities;

4. _preflight.css

5.  vscode  插件 可以直接搜索 Tailwindcss 下载敲代码 样式提示插件  

6. 可以直接在 Tailwindcss 官网直接搜索样式  ，非常方便

7 . 常见写法样式举例 h-30 为 height:30  也支持自定义 h-[30px] w-[30px]  text-[30px]   ，一般在官网搜索 后面会给出值自定义例子
