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@keyframes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
