Tailwind CSS 是什么

Tailwind CSS 是一个高度可定制的基础层 CSS 框架，它为您提供了构建定制化设计所需的所有构建块，而无需重新覆盖任何内建于框架中的设计风格。

为什么要使用 Tailwind CSS

• 可定制开发
• 天生就支持响应式布局
• 组件友好
• ...

首先安装 Vue

npm install -g @vue/cli

初始化 Vue 项目，我们初始化一个名为 tailwind 的项目

vue create tailwind

中间省略若干步骤，可以直接默认就行

? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, PWA, Router, Vuex, Linter
? Use history mode for router? (Requires proper server setup for index fallback in production) Yes
? Pick a linter / formatter config: Basic
? Pick additional lint features: Lint on save, Lint and fix on commit
? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated config files
? Save this as a preset for future projects? No

安装 Tailwind CSS

接下来我们将 Tailwind CSS 集成到我们的项目中

cd tailwind
npm install tailwindcss

新建 tailwind.css,在 src/assets 新建 css 文件夹，并新建 tailwind.css

touch src/assets/css/tailwind.css

之后再 tailwind.css 文件中，添加如下内容:

@tailwind base;

@tailwind components;

@tailwind utilities;

修改 main.js 引入 import "./assets/css/tailwind.css"

import Vue from 'vue'
import App from './App.vue'
import './registerServiceWorker'
import router from './router'
import store from './store'

import "./assets/css/tailwind.css"

Vue.config.productionTip = false

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount('#app')

创建 Tailwind 配置文件

npx tailwind init
or
npx tailwind init --full

输完命令会有如下输出，即代表创建成功

tailwindcss 1.1.4

✅ Created Tailwind config file: tailwind.config.js

新建 postcss.config.js 文件

touch postcss.config.js

填入以下内容：

const purgecss = require('@fullhuman/postcss-purgecss')({
    content: [
      './src/**/*.html',
      './src/**/*.vue',
      './src/**/*.jsx',
    ],

    // Include any special characters you're using in this regular expression
    defaultExtractor: content => content.match(/[\w-/:]+(?<!:)/g) || []
  })

module.exports = {
    plugins: [
      require('tailwindcss'),
      require('autoprefixer'),
      ...process.env.NODE_ENV === 'production'
      ? [purgecss]
      : []
    ]
  }

以上步骤，大致就可以将 Tailwind CSS 引入到 Vue 项目中了。接下来我们启动项目

npm run serve

测试

我们直接修改 App.vue 文件，来看看效果

<template>
  <div class="flex items-center justify-center align-middle">
    <div class="flex h-screen">
      <div class="m-auto">
        <div class="md:flex">
          <div class="md:flex-shrink-0">
            <img
              class="rounded-lg md:w-56"
              src="https://images.unsplash.com/photo-1556740738-b6a63e27c4df?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=2550&q=80"
              alt="Woman paying for a purchase"
            />
          </div>
          <div class="mt-4 md:mt-0 md:ml-6">
            <div class="uppercase tracking-wide text-sm text-indigo-600 font-bold">Marketing</div>
            <a
              href="#" target="_blank" rel="external nofollow" 
              class="block mt-1 text-lg leading-tight font-semibold text-gray-900 hover:underline"
            >Finding customers for your new business</a>
            <p
              class="mt-2 text-gray-600"
            >Getting a new business off the ground is a lot of hard work. Here are five ideas you can use to find your first customers.</p>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

<style>
</style>
