css3实现好看的气泡按钮动画特效
CSS3 在我们网页设计中是最关键的一环,为什么这么说呢?我们在浏览别人的网站时,经常会看到特别好看的动画效果,比如一个按钮啊,一个图片啊,每次看到都能够让人有种赏心悦目的感觉,这就使网站更具有吸引力和互动性。接下来我就用 css3 的一些属性来完成点击按钮气泡动画特效。
先看 gif 效果图:
是不是很酷炫,哈哈,别着急,干货马上献上。
HTML 代码:
<buttonclass="bubbly-button">Clickme!</button>
关键CSS 代码:
body { font-size: 16px; font-family: 'Helvetica', 'Arial', sans-serif; text-align: center; background-color: #f8faff; } .bubbly-button { font-family: 'Helvetica', 'Arial', sans-serif; display: inline-block; font-size: 1em; padding: 1em 2em; margin-top: 100px; margin-bottom: 60px; -webkit-appearance: none; appearance: none; background-color: #ff0081; color: #fff; border-radius: 4px; border: none; cursor: pointer; position: relative; transition: transform ease-in 0.1s, box-shadow ease-in 0.25s; box-shadow: 0 2px 25px rgba(255, 0, 130, 0.5); } .bubbly-button:focus { outline: 0; } .bubbly-button:before, .bubbly-button:after { position: absolute; content: ''; display: block; width: 140%; height: 100%; left: -20%; z-index: -1000; transition: all ease-in-out 0.5s; background-repeat: no-repeat; } .bubbly-button:before { display: none; top: -75%; background-image: radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, transparent 20%, #ff0081 20%, transparent 30%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, transparent 10%, #ff0081 15%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%); background-size: 10% 10%, 20% 20%, 15% 15%, 20% 20%, 18% 18%, 10% 10%, 15% 15%, 10% 10%, 18% 18%; } .bubbly-button:after { display: none; bottom: -75%; background-image: radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, transparent 10%, #ff0081 15%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%), radial-gradient(circle, #ff0081 20%, transparent 20%); background-size: 15% 15%, 20% 20%, 18% 18%, 20% 20%, 15% 15%, 10% 10%, 20% 20%; } .bubbly-button:active { transform: scale(0.9); background-color: #e60074; box-shadow: 0 2px 25px rgba(255, 0, 130, 0.2); } .bubbly-button.animate:before { display: block; animation: topBubbles ease-in-out 0.75s forwards; } .bubbly-button.animate:after { display: block; animation: bottomBubbles ease-in-out 0.75s forwards; } @keyframes topBubbles { 0% { background-position: 5% 90%, 10% 90%, 10% 90%, 15% 90%, 25% 90%, 25% 90%, 40% 90%, 55% 90%, 70% 90%; } 50% { background-position: 0% 80%, 0% 20%, 10% 40%, 20% 0%, 30% 30%, 22% 50%, 50% 50%, 65% 20%, 90% 30%; } 100% { background-position: 0% 70%, 0% 10%, 10% 30%, 20% -10%, 30% 20%, 22% 40%, 50% 40%, 65% 10%, 90% 20%; background-size: 0% 0%, 0% 0%, 0% 0%, 0% 0%, 0% 0%, 0% 0%; } } @keyframes bottomBubbles { 0% { background-position: 10% -10%, 30% 10%, 55% -10%, 70% -10%, 85% -10%, 70% -10%, 70% 0%; } 50% { background-position: 0% 80%, 20% 80%, 45% 60%, 60% 100%, 75% 70%, 95% 60%, 105% 0%; } 100% { background-position: 0% 90%, 20% 90%, 45% 70%, 60% 110%, 75% 80%, 95% 70%, 110% 10%; background-size: 0% 0%, 0% 0%, 0% 0%, 0% 0%, 0% 0%, 0% 0%; } }
当然需要一点javascript 代码:
var animateButton = function(e) { e.preventDefault; //reset animation e.target.classList.remove('animate'); e.target.classList.add('animate'); setTimeout(function(){ e.target.classList.remove('animate'); },700); }; var classname = document.getElementsByClassName("bubbly-button"); for (var i = 0; i < classname.length; i++) { classname[i].addEventListener('click', animateButton, false); }
以上代码实现不难,关键都是在 CSS3 这一块儿,所以看不懂一些属性的童鞋下去好好补补 CSS3 这一块儿的知识,相信你也能玩转 CSS3 动画特效,有了它,我们的网页无疑是锦上添花,画龙点睛呐!!哈哈
结束语:
代码这种东西不仅要学还要动手去敲的,时间长了就会显得生疏,好了,大家可以下去试试了。
