    -webkit-animation:mymove 3s;

@keyframes mymove
{
    from {top:0px;}
    to {top:200px;}
}

@-webkit-keyframes mymove /* Safari and Chrome */
{
    from {top:0px;}
    to {top:200px;}

css3动画不循环可以使用animation-iteration-count属性定义动画的播放次数。

只需要在动画中添加“animation-iteration-count:infinite;”或者不写，即可实现无限次循环。
animation-iteration-count :n;定义动画的播放n次。

.state {
    position: absolute; bottom: 65px; right: 180px; z-index: 100000000;
}

.state p {
    padding: 5px 50px 5px 20px;
    font-size: 13px;
    color: #333;
    font-weight: bold;
    border-radius: 25px;
}

.state.into p {
    background: #999;
}

.state.out p {
    background: #FF5465;
}

.state {
    opacity: 0;
    animation: animate2 2s ease-in-out infinite;
    -webkit-animation: animate2 2s ease-in-out infinite;
    animation-iteration-count:1;
    -webkit-animation-iteration-count:1;
}

@keyframes animate2 {
    0% {
        bottom: 65px;
    }

    30% {
        bottom: 95px;
        opacity: 1;
    }

    70% {
        bottom: 135px;
        opacity: 0.8;
    }

    100% {
        bottom: 170px;
        opacity: 0;
    }
}
<div class="state">
    <p>走你!</p>
</div>
