纯css3波浪动画

    非常漂亮的基于CSS3动画实现的波浪翻滚的动画效果，放在网页上，肯定能让网页效果更佳绚烂。我爱模板网之前做的一个手机APP下载页面就用了这种效果。使用方法请往下看。
1、将下载下来的img里面的图片放入项目中，一共三张图。

2、将下面的css3代码放入您的css文件中：

@keyframes move_wave {
    0% {
        transform: translateX(0) translateZ(0) scaleY(1)
    }
    50% {
        transform: translateX(-25%) translateZ(0) scaleY(0.55)
    }
    100% {
        transform: translateX(-50%) translateZ(0) scaleY(1)
    }
}
.waveWrapper {
    overflow: hidden;
    position: absolute;
    left: 0;
    right: 0;
    bottom: 0;
    top: 0;
    margin: auto;
}
.waveWrapperInner {
    position: absolute;
    width: 100%;
    overflow: hidden;
    height: 100%;
    bottom: -1px;
    background-image: linear-gradient(to top, #86377b 20%, #27273c 80%);
}
.bgTop {
    z-index: 15;
    opacity: 0.5;
}
.bgMiddle {
    z-index: 10;
    opacity: 0.75;
}
.bgBottom {
    z-index: 5;
}
.wave {
    position: absolute;
    left: 0;
    width: 200%;
    height: 100%;
    background-repeat: repeat no-repeat;
    background-position: 0 bottom;
    transform-origin: center bottom;
}
.waveTop {
    background-size: 50% 100px;
}
.waveAnimation .waveTop {
  animation: move-wave 3s;
   -webkit-animation: move-wave 3s;
   -webkit-animation-delay: 1s;
   animation-delay: 1s;
}
.waveMiddle {
    background-size: 50% 120px;
}
.waveAnimation .waveMiddle {
    animation: move_wave 10s linear infinite;
}
.waveBottom {
    background-size: 50% 100px;
}
.waveAnimation .waveBottom {
    animation: move_wave 15s linear infinite;
}

3、将下面的html代码放入您需要放的位置。大小直接修改上面的css样式即可。背景颜色如果不想要，直接从上面的css样式中删除：

<div class="waveWrapper waveAnimation">
  <div class="waveWrapperInner bgTop">
    <div class="wave waveTop" style="background-image: url('img/wave-top.png')"></div>
  </div>
  <div class="waveWrapperInner bgMiddle">
    <div class="wave waveMiddle" style="background-image: url('img/wave-mid.png')"></div>
  </div>
  <div class="waveWrapperInner bgBottom">
    <div class="wave waveBottom" style="background-image: url('img/wave-bot.png')"></div>
  </div>
</div>
