35 在Vue3中如何通过SCSS编写样式

概述

在Vue3中通过SCSS编写样式并不难,这节课我们来简单的学习一下。

本节课需要依赖一个第三方库,我们先安装:

yarn add sass -D

基本用法

我们创建src/components/Demo35.vue,代码如下:

<template>
  <button>这是一个按钮button>
template>
<style lang="scss">
button {
  color: red;
  width: 100px;
  height: 30px;
  padding: 5px;
}
style>

接着,我们修改src/App.vue:

<script setup>
import Demo from "./components/Demo35.vue"
script>
<template>
  <h1>欢迎跟着Python私教一起学习Vue3入门课程h1>
  <hr>
  <demo/>
template>

然后,我们浏览器访问:http://localhost:5173/
