页面布局

机器人样式参考了下图，通过css拼造型的方式进行实现。部分还原了设计图

 <div class="tianxian"></div> .tianxian{    width: 35px;    height: 35px;    border-radius: 50%;    background: #0e58cc;    position: absolute;    left: 0;    right: 0;    top: 0;    margin: auto;  }  .tianxian::after{    content: &#39;&#39;;    display: block;    width: 5px;    height: 10px;    border-radius: 12px;    background: #fff;    position: absolute;    top: 10px;    left: 5px;    transform: rotateZ(20deg);  }

整体布局采用绝对定位布局利用整个头部，实现耳朵和眼睛的定位

<div class="head">      <div class="erduo"></div>      <div class="erduo"></div>      <div class="face">        <div class="eye"></div>        <div class="eye"></div>      </div>    </div>

 box-shadow: -5px -5px 30px 1px #0075af inset;

基于浏览器提供的SpeechSynthesisUtterance Api进行实现

SpeechSynthesisUtterance基本属性

SpeechSynthesisUtterance.text基本方法

为按钮添加点击事件，获取input输入框的值，并进行播放，添加眼睛动画，并在播放结束的回调移除眼睛动画

$(&#39;#btn&#39;).click(function () {      let text = $(&#39;#input&#39;).val()      if (text) {        $(&#39;.eye&#39;).addClass(&#39;shine&#39;)      }      let u = new window.SpeechSynthesisUtterance()      u.text = text      u.lang = &#39;zh&#39;      u.rate = 0.7      u.onend = function () {        $(&#39;.eye&#39;).removeClass(&#39;shine&#39;)      }      speechSynthesis.speak(u)    })

动画类：

 .shine {    animation: shine 1s linear infinite;  }  @keyframes shine {    0%{      height: 100px;    }    100%{      height: 0px;    }  }
