純CSS3怎麼實現波浪效果? (程式碼範例)

        隨著前端技術的不斷發展與進步,介面互動的樣式要求和美感也越來越高,許多網頁的互動都加上了css3動畫,這裡作者跟大家分享一個前端開發必掌握的一個CSS3波浪效果,趕緊學起來吧,加在自己開發網頁的底部,給頁面增加一點活潑的氣息~【推薦學習:css視頻教程


CSS3波浪效果

        這是使用SVG 與CSS 動畫所製作的波浪效果,上半部是藍色(可修改成其他顏色)漸變的背景顏色,下半部是波浪,有四條波浪在不停的來回起伏,非常逼真。此波浪效果可用於大部分頁面的底部,使頁面增加一點活潑的氣息。 。

1.Html建置

#程式碼如下(範例):

1431eb25a37e2a6aac99f7b4d6d6b2f7這部分就是波浪的svg,有四條波浪在不停的來回起伏,效果非常逼真

 
		<div class="header">
			<div class="inner-header flex">
				<h1>简单的 CSS3 波浪效果</h1>
			</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編寫

程式碼如下(範例):

這裡透過CSS3animation動畫屬性來控制四條線條在不停的來回起伏,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%);
/* 	background: #FFAFBD;  
	background: -webkit-linear-gradient(to right, #ffc3a0, #FFAFBD);  
	background: linear-gradient(to right, #ffc3a0, #FFAFBD); 
 */
    color: white;
}
 
 
.inner-header {
    height: 65vh;
    width: 100%;
    margin: 0;
    padding: 0;
}
 
 
 
.waves {
    position: relative;
    width: 100%;
    height: 15vh;
    margin-bottom: -7px; /*Fix for safari gap*/
    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;
}
 
/* Animation */
 
.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);
    }
}
/*Shrinking for mobile*/
@media (max-width: 768px) {
    .waves {
        height: 40px;
        min-height: 40px;
    }
    .content {
        height: 30vh;
    }
    h1 {
        font-size: 24px;
    }
}
