HTML部分

建立一个div，id为wavesDIV，之后使用svg绘制一个图形出来，此时这个图形还是不会懂的，我们需要使用animation来让他动起来

<div id="wavesDIV" style="display: block;">
        <svg class="waves" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 24 150 28" preserveAspectRatio="none" shape-rendering="auto">
            <defs>
                <path id="gentle-wave" d="M-160 44c30 0 58-18 88-18s 58 18 88 18 58-18 88-18 58 18 88 18 v44h-352z"></path>
            </defs>
            <g class="parallax">
                <use xlink:href="#gentle-wave" x="48" y="-2" fill="rgba(125,165,191,0.3)"></use>
                <use xlink:href="#gentle-wave" x="48" y="3" fill="rgba(125,165,191,0.5)"></use>
                <use xlink:href="#gentle-wave" x="48" y="5" fill="rgba(125,165,191,0.7)"></use>
                <use xlink:href="#gentle-wave" x="48" y="12" fill="rgba(125,165,191,1)"></use>
            </g>
        </svg>
    </div>

CSS部分

使用设定动画，使用animation调用

#wavesDIV{
  position: fixed;
  bottom: 0;
  width: 100%;
  display:block;
  height:20vh;
  background-color:rgb(125,165,191);
  animation: move-out 2s cubic-bezier(0,.98,.97,1) forwards;
}
.waves { 
  position:relative; 
  width: 100%; 
  height:15vh; 
  margin-top:-15vh; 
  min-height:100px; 
  max-height:150px; 
}
.parallax > use { 
  animation: move-forever 25s cubic-bezier(.55, .5, .45, .5) infinite; 
} 
.parallax > use:nth-child(1) { 
  animation-delay: -2s; 
  animation-duration: 7s; 
} 
.parallax > use:nth-child(2) { 
  animation-delay: -3s; 
  animation-duration: 10s; 
} 
.parallax > use:nth-child(3) { 
  animation-delay: -4s; 
  animation-duration: 13s; 
} 
.parallax > use:nth-child(4) { 
  animation-delay: -5s; 
  animation-duration: 20s; 
} 
@keyframes move-forever { 
  0% { 
    transform: translate3d(-90px, 0, 0); 
  } 
  100% { transform: translate3d(85px, 0, 0); 
  } 
}
@keyframes move-out { 
  0% { 
    transform: translateY(400%); 
  } 
  100% { transform: translateY(0%); 
  } 
}
home.php?mod=space&uid=945662 (max-width: 768px) { 
  .waves { 
    height:40px; min-height:40px; 
  } 
}

当然如果在中间加多点，譬如说10%,20%,30%,40%,50%,60%，动态会更强烈
