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 pxlet 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
