是不是很酷炫,哈哈,别着急,干货马上献上。

HTML代码

  <buttonclass="bubbly-button">Clickme!</button>

关键CSS代码

body {
  font-size: 16px;
  font-family: 'Helvetica', 'Arial', sans-serif;
  text-align: center;
  background-color: #f8faff;
}

.bubbly-button {
  font-family: 'Helvetica', 'Arial', sans-serif;
  display: inline-block;
  font-size: 1em;
  padding: 1em 2em;
  margin-top: 100px;
  margin-bottom: 60px;
  -webkit-appearance: none;
  appearance: none;
  background-color: #ff0081;
  color: #fff;
  border-radius: 4px;
  border: none;
  cursor: pointer;
  position: relative;
  transition: transform ease-in 0.1s, box-shadow ease-in 0.25s;
  box-shadow: 0 2px 25px rgba(255, 0, 130, 0.5);
}
.bubbly-button:focus {
  outline: 0;
}
.bubbly-button:before, .bubbly-button:after {
  position: absolute;
  content: '';
  display: block;
  width: 140%;
  height: 100%;
  left: -20%;
  z-index: -1000;
  transition: all ease-in-out 0.5s;
  background-repeat: no-repeat;
}
.bubbly-button:before {
  display: none;
  top: -75%;
  background-image: radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, transparent 20%, #ff0081 20%, transparent 30%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, transparent 10%, #ff0081 15%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%);
  background-size: 10% 10%, 20% 20%, 15% 15%, 20% 20%, 18% 18%, 10% 10%, 15% 15%, 10% 10%, 18% 18%;
}
.bubbly-button:after {
  display: none;
  bottom: -75%;
  background-image: radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, transparent 10%, #ff0081 15%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%);
  background-size: 15% 15%, 20% 20%, 18% 18%, 20% 20%, 15% 15%, 10% 10%, 20% 20%;
}
.bubbly-button:active {
  transform: scale(0.9);
  background-color: #e60074;
  box-shadow: 0 2px 25px rgba(255, 0, 130, 0.2);
}
.bubbly-button.animate:before {
  display: block;
  animation: topBubbles ease-in-out 0.75s forwards;
}
.bubbly-button.animate:after {
  display: block;
  animation: bottomBubbles ease-in-out 0.75s forwards;
}

@keyframes topBubbles {
  0% {
    background-position: 5% 90%, 10% 90%, 10% 90%, 15% 90%, 25% 90%, 25% 90%, 40% 90%, 55% 90%, 70% 90%;
  }
  50% {
    background-position: 0% 80%, 0% 20%, 10% 40%, 20% 0%, 30% 30%, 22% 50%, 50% 50%, 65% 20%, 90% 30%;
  }
  100% {
    background-position: 0% 70%, 0% 10%, 10% 30%, 20% -10%, 30% 20%, 22% 40%, 50% 40%, 65% 10%, 90% 20%;
    background-size: 0% 0%, 0% 0%,  0% 0%,  0% 0%,  0% 0%,  0% 0%;
  }
}
@keyframes bottomBubbles {
  0% {
    background-position: 10% -10%, 30% 10%, 55% -10%, 70% -10%, 85% -10%, 70% -10%, 70% 0%;
  }
  50% {
    background-position: 0% 80%, 20% 80%, 45% 60%, 60% 100%, 75% 70%, 95% 60%, 105% 0%;
  }
  100% {
    background-position: 0% 90%, 20% 90%, 45% 70%, 60% 110%, 75% 80%, 95% 70%, 110% 10%;
    background-size: 0% 0%, 0% 0%,  0% 0%,  0% 0%,  0% 0%,  0% 0%;
  }
}

当然需要一点javascript代码

var animateButton = function(e) {

  e.preventDefault;
  //reset animation
  e.target.classList.remove('animate');
  
  e.target.classList.add('animate');
  setTimeout(function(){
    e.target.classList.remove('animate');
  },700);
};

var classname = document.getElementsByClassName("bubbly-button");

for (var i = 0; i < classname.length; i++) {
  classname[i].addEventListener('click', animateButton, false);
}

以上代码实现不难,关键都是在CSS3这一块儿,所以看不懂一些属性的童鞋下去好好补补CSS3这一块儿的知识,相信你也能玩转CSS3动画特效,有了它,我们的网页无疑是锦上添花,画龙点睛呐!!哈哈

结束语:

代码这种东西不仅要学还要动手去敲的,时间长了就会显得生疏,好了,大家可以下去试试了。
