CSS--房间开关灯泡效果

概要

层叠样式表(英文全称：Cascading Style Sheets)是一种用来表现HTML（标准通用标记语言的一个应用）或XML（标准通用标记语言的一个子集）等文件样式的计算机语言。CSS不仅可以静态地修饰网页，还可以配合各种脚本语言动态地对网页各元素进行格式化。熟练掌握CSS的基本原理可以实现更好的页面交互效果，提升用户的使用体验。

代码实现

新建文件夹light-bulb，light-bulb下新建index.html和style.css文件，新建audio文件夹用于存放开关音效

目录结构

/**
light-bulb
   ├─ audio
   ├─ index.html
   └─ style.css
*/

index.html代码

<!DOCTYPE html>

    <div class="bulb">

      <span></span>
    </div>
    <div class="switch">
      <div class="btn"></div>
    </div>
    <audio id="audio" src="./audio/switch.mp3" autostart="false"></audio>
  </div>
  <script>
    let btn = document.querySelector('.btn')
    let body = document.querySelector('body')
    let audio = document.querySelector('#audio')
    btn.onclick = function () {
      body.classList.toggle('on')
      audio.play()
    }
  </script>
</body>
</html>
