CSS3波浪效果
这是使用 SVG 和 CSS 动画制作的波浪效果，上半部分是蓝色（可修改成其他颜色）渐变的背景颜色，下半部分就是波浪，有四条波浪在不停的来回起伏，非常逼真。该波浪效果可用于大部分页面的底部，使页面增加一点活泼的气息。。
1.Html构建
代码如下（示例）：
<div class="inner_header"> 填充蓝色（可修改成其他颜色）渐变的背景颜色
<div class="waves">这部分就是波浪的svg，有四条波浪在不停的来回起伏，效果非常逼真
<div class="header">
<div class="inner-header flex">
<h2>简单的 CSS3 波浪效果</h2>
</div>
<div>
<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>
</div>
</div>2.CSS编写
代码如下（示例）：
这里通过CSS3的animation动画属性来控制四条线条在不停的来回起伏，形成波浪效果
.header {
position: relative;
text-align: center;
background: linear-gradient(60deg, rgba(84, 58, 183, 1) 0%, rgba(0, 172, 193, 1) 100%);
color: white;
}
.inner-header {
height: 65vh;
width: 100%;
margin: 0;
padding: 0;
}
.waves {
position: relative;
width: 100%;
height: 15vh;
margin-bottom: -7px;
min-height: 100px;
max-height: 150px;
}
.content {
position: relative;
height: 20vh;
text-align: center;
background-color: white;
}
.content a {
margin: 0 5px;
font-size: 12px;
color: #333;
}
.content a:hover {
color: #000;
}
.parallax > use {
animation: move-forever 25s cubic-bezier(0.55, 0.5, 0.45, 0.5) 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);
}
}
@media (max-width: 768px) {
.waves {
height: 40px;
min-height: 40px;
}
.content {
height: 30vh;
}
h2 {
font-size: 24px;
}
