css部分：

html {
  font-size: 10px;
  background: url('../img/background.jpg') bottom center;
  background-size: cover;
}

body,html {
  margin: 0;
  padding: 0;
  font-family: sans-serif;
}

.keys {
  display: flex;
  flex: 1;
  min-height: 100vh;
  align-items: center;
  justify-content: center;
}

.key {
  border: .4rem solid black;
  border-radius: .5rem;
  margin: 1rem;
  font-size: 1.5rem;
  padding: 1rem .5rem;
  transition: all .07s ease;
  width: 10rem;
  text-align: center;
  color: white;
  background: rgba(0,0,0,0.4);
  text-shadow: 0 0 .5rem black;
}

.playing {
  transform: scale(1.1);
  border-color: #ffc600;
  box-shadow: 0 0 1rem #ffc600;
}

kbd {
  display: block;
  font-size: 4rem;
}

.sound {
  font-size: 1.2rem;
  text-transform: uppercase;
  letter-spacing: .1rem;
  color: #ffc600;
}

  //第一步实现按下键盘实现，声音的播放
          
          window.addEventListener("keydown",function(e){
               console.log(e.keyCode);
               const audio=document.querySelector(`audio[data-key="${e.keyCode}"]`);
               const key=document.querySelector(`div[data-key="${e.keyCode}"]`)
               //每次播放完初始化
               if (!audio) return;
               audio.currentTime = 0;
               audio.play();

                 key.classList.add('playing');

                 setTimeout(function(){
                   key.classList.remove('playing');
                 },70);
               
               //按键之后移出效果

          })
