汕头SEO（svg使用css3波浪动态效果）

汕头SEO：最近一点哥正在开发一款情侣模板，在制作一个波浪效果时费了半天时间，毕竟js不是很熟，然后敲了半天，终于用svg+css3搞定了这个波浪效果；截图

波浪动态效果是这样的：

div的svg

    <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" />
		</defs>
		<g class="parallax">
			<use xlink:href="#gentle-wave" x="48" y="0" fill="rgba(255,255,255,0.7" />
			<use xlink:href="#gentle-wave" x="48" y="3" fill="rgba(255,255,255,0.5)" />
			<use xlink:href="#gentle-wave" x="48" y="5" fill="rgba(255,255,255,0.3)" />
			<use xlink:href="#gentle-wave" x="48" y="7" fill="#fff" />
		</g>
	</svg>

css代码

.waves {
  position:relative;
  width: 100%;
  height:15vh;
  top: -80px;
  margin-bottom:-7px; /*Fix for safari gap*/
  min-height:100px;
  max-height:150px;
}

/* Animation */

.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);
  }
}
/*Shrinking for mobile*/
@media (max-width: 768px) {
  .waves {
    height:40px;
    min-height:40px;
  }
  .content {
    height:30vh;
  }
  h1 {
    font-size:24px;
  }
}
