每天都是新的一天，每天都是快乐的一天，每天都应当给自己一个笑脸 。当你手上没有镜子，自拍神器又刚好没电，那就用你的web开发技术给自己码一个出来吧！主要的还是css3的应用，记得用好点的浏览器哦 。

  <div class="eye ER"><div class="pupil"></div></div>
/div>

</div>

css：

* {
  box-sizing: border-box;
}

.container {
  width: 80%;
  min-height: 400px;
  background-color: #ee3a4c;
  overflow: auto;
  display: block;
  margin: 0 auto;
}

.eyes {
  width: 400px;
  display: block;
  margin: 0 auto;
  text-align: center;
  margin-top: 66.66667px;
  margin-bottom: 25px;
}

.eye {
  height: 100px;
  width: 100px;
  background-color: #ee3a4c;
  border: 4px solid white;
  border-radius: 100%;//变圆形
  display: inline-block;
  margin: 0 20px;
  position: relative; //相对定位
  padding: 20px;
  overflow: hidden;
}
.eye .pupil {
  height: 25px;
  width: 25px;
  border-radius: 100%; //变圆 
  display: inline-block;
  background-color: white;
  position: absolute;
  margin-left: -10px;
  left: 50px;
  margin: 10px;
}

.smile {
  height: 100px;
  width: 200px;
  border-radius: 0 0 200px 200px; //半圆
  background: #770f1a;
  margin: 0 auto;
  overflow: hidden;
  transition: all .4s; //动画效果
  transform-origin: center;
}
.smile:hover {
  transition: all .4s; height: 33.33333px;
  width: 33.33333px;
  border-radius: 100%;
  margin-top: 50px;
}
.smile:hover .teeth {
  margin-left: -25px;
  margin-top: -40px;
  transition: all .4s;
}
.smile:hover .tongue {
  transition: all .4s;
  margin-left: -50px;
  /*margin-top: $tongueDimensions*2;*/
}
.smile .teeth {
  background-color: #fff;
  transition: all .4s;
  height: 33.33333px;
  width: 33.33333px;
  margin-left: 56.66667px;
  position: relative;
}
.smile .teeth:after {
  content: "";    //一个变成两 ：after
  background-color: #fff;
  height: 33.33333px;
  width: 33.33333px;
  position: absolute;
  left: 50px;
  top: 0;
  z-index: 10000;
}
.smile .tongue {
  transition: all .4s;
  height: 100px;
  width: 100px;
  background-color: pink;
  border-radius: 100%;
  margin-top: 40px;
  margin-left: 15px;
  display: inline-block;
  position: relative;
}
.smile .tongue:after {
  content: '';
  height: 100px;
  width: 100px;
  background-color: pink;
  border-radius: 100%;
  display: inline-block;
  position: absolute;
  left: 50px;
  /*margin-top: 0;
    margin-left: -($tongueDimensions/3);*/
}

js：

var limitX = 50, limitY = 50;
var containerW = $('.container').width();
var containerH = $('.container').height();
$( ".container" ).mousemove(function( e ) {
  var mouseY = Math.min(e.clientY/(containerH*.01), limitY);
  var mouseX = Math.min(e.clientX/(containerW*.01), limitX);
  $('.pupil').css('top', mouseY);
  $('.pupil').css('left', mouseX);
  console.log(e.clientY+'  '+e.clientX);//眼球跟随鼠标的效果，是不是也很简单
});
