css3动画语法 loading效果、音乐震动条实例

2018-2-1

动画这个平常用的也很多，主要是做一个预设的动画。和一些页面交互的动画效果，结果和过渡应该一样，让页面不会那么生硬！

3-1.语法

animation：动画名称，一个周期花费时间，运动曲线（默认ease），动画延迟（默认0），播放次数（默认1），是否反向播放动画（默认normal），是否暂停动画（默认running）

栗子1

/*执行一次logo2-line动画，运动时间2秒，运动曲线为 linear*/
animation: logo2-line 2s linear;

栗子2

/*2秒后开始执行一次logo2-line动画，运动时间2秒，运动曲线为 linear*/
animation: logo2-line 2s linear 2s;

栗子3

/*无限执行logo2-line动画，每次运动时间2秒，运动曲线为 linear，并且执行反向动画*/
animation: logo2-line 2s linear alternate infinite;

还有一个重要属性

animation-fill-mode : none | forwards | backwards | both;
/*none：不改变默认行为。    
forwards ：当动画完成后，保持最后一个属性值（在最后一个关键帧中定义）。    
backwards：在 animation-delay 所指定的一段时间内，在动画显示之前，应用开始属性值（在第一个关键帧中定义）。 
both：向前和向后填充模式都被应用。  */

3-2.logo展示动画

这个是我用公司logo写的动画，没那么精细

代码如下

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="reset.css">
</head>
<style>
.logo-box{
    width: 600px;
    margin: 100px auto;
    font-size: 0;
    position: relative;
}
.logo-box div{
    display: inline-block;
}
.logo-box .logo-text{
    margin-left: 10px;
}
.logo-box .logo1{
    animation: logo1 1s ease-in 2s;
    animation-fill-mode:backwards;
}
.logo-box .logo-text{
    animation: logoText 1s ease-in 3s;
    animation-fill-mode:backwards;
}
.logo-box .logo2{
    position: absolute;
    top: 20px;
    left: 20px;
    animation: logo2-middle 2s ease-in;
}
.logo-box .logo2 img{
    animation: logo2-line 2s linear;
}
@keyframes logo1 {
    0%{
        transform:rotate(180deg);
        opacity: 0;
    }
    100%{
        transform:rotate(0deg);
        opacity: 1;
    }
}
@keyframes logoText {
    0%{
        transform:translateX(30px);
        opacity: 0;
    }
    100%{
        transform:translateX(0);
        opacity: 1;
    }
}
@keyframes logo2-line {
    0% { transform: translateX(200px)}
    25% { transform: translateX(150px)}
    50% { transform: translateX(100px)}
    75% { transform: translateX(50px)}
    100% { transform: translateX(0); }
}

@keyframes logo2-middle {
    0% { transform: translateY(0);     }
    25% { transform: translateY(-100px);     }
    50% { transform: translateY(0);     }
    75% { transform: translateY(-50px);     }
    100% { transform: translateY(0); }
}
</style>
<body>
<div class="logo-box">
<div class="logo1"><img src="logo1.jpg"/></div>
<div class="logo2"><img src="logo2.jpg"/></div>
<div class="logo-text"><img src="logo3.jpg"/></div>
</div>

<div class="wraper"><div class="item"></div></div>

</body>
</html>
