如何在CSS中制作流畅的动画？

标签： html css html5 css3 animation

我使用了translate（）的动画。代码链接位于Bouncy animation

但它突然从底部开始。如何让它顺利开始。还要注意动画之间的扭曲。如何删除此类错误？

代码如下：

	body{background: #92348A;
		font-family:'Helvetica Neue',Arial, Helvetica, sans-serif;}
		
	.wrapper{ margin-left:370px;
			margin-top:195px;
			position:absolute;
			}
	p{ font-family: "Comic Sans MS", cursive;
		font-weight:900;
	
		}
	.one{width:50px;
		height:50px;
		float:left;
		margin:0.5em;
		position:relative;
		border-radius:100%;
		background: #F00;
		text-align:center;
		-webkit-animation:bounce 2s cubic-bezier(0.1,0.1,.3,1.9) 0.2s infinite ;
		}	
	.two{width:50px;
		height:50px;
		float:left;
		margin:1em;
		position:relative;
		border-radius:100%;
		background: #9D1A76;
		text-align:center;
		-webkit-animation:bounce 2s cubic-bezier(0.1,0.1,.3,1.9) 0.38s infinite;}	
	.three{width:50px;
		height:50px;
		float:left;
		margin:1em;
		position:relative;
		border-radius:100%;
		background: #FF0080;
		text-align:center;
		-webkit-animation:bounce 2s cubic-bezier(0.1,0.1,.3,1.9) 0.3s infinite;}	
	.four{width:50px;
		height:50px;
		float:left;
		margin:1em;
		position:relative;
		border-radius:100%;
		background: #FF0;
		text-align:center;
		-webkit-animation:bounce 2s cubic-bezier(0.1,0.1,.3,1.9) 0.35s infinite;}	
	.five{width:50px;
		height:50px;
		float:left;
		margin:1em;
		position:relative;
		border-radius:100%;
		background: #0ECAF1;
		text-align:center;
		-webkit-animation:bounce 2s cubic-bezier(0.1,0.1,.3,1.9) 0.23s infinite;}	
	.six{width:50px;
		height:50px;
		float:left;
		margin:1em;
		position:relative;
		border-radius:100%;
		background: #0BF451;
		text-align:center;
		-webkit-animation:bounce 2s cubic-bezier(0.1,0.1,.3,1.9) 0.1s infinite;}
	.seven{width:50px;
		height:50px;
		float:left;
		margin:1em;
		position:relative;
		border-radius:100%;
		background: #645CF1;
		text-align:center;
		-webkit-animation:bounce 2s cubic-bezier(0.1,0.1,.3,1.9) 0.14s infinite;}	
		
	@-webkit-keyframes bounce{
				2%{ transform: translateY(120px);}
				50%{ transform:translateY(-90px);}
				100%{ transform:translateY(120px);}
				}
<body>

	<div class="wrapper">
    	<div class="one">
        	<p>W</p>
        </div>

@harcos答案是正确的，但没有顺利开始。 添加transform:translateY(-90px); 在动画开始的地方渲染所有不同的动画类。
