像CSS Transitions一样下雨

Question

我希望标签无限下降.我试图通过CSS转换来做到这一点,但无法让它工作.

我希望.fall不断下雨.我怎样才能让它发挥作用？

很抱歉提出一个摇摆问题,但可能是小提琴将清除我想要完成的事情.

的jsfiddle

HTML

<div class='rain'>
    <p class='fallSec'>
        < $ " " 1 0 1 0 0 0 $ 1 0 2 ( { $ 1 0=) 0 1 0 0 0 1 }
    </p>
</div>

CSS

.rainSec {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    overflow: hidden;
}
.rainSec .fall {
    width: 20px;
    color: white;
    font-size: 36px;
    float: left;
    margin: 10px;
    -webkit-animation: fadeInDown 10s infinite;
    animation: fadeInDown 10s infinite;
}
.rain {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    overflow: hidden;
}
.rain .fallSec {
    color: blue;
    width: 20px;
    font-size: 36px;
    float: left;
    margin: 10px;
    -webkit-animation: fadeInDown 8s infinite;
    animation: fadeInDown 8s infinite;
    transition-delay: 8s;
}
@-webkit-keyframes fadeInDown {
    0% {
        -webkit-transform: translateY(-100%);
    }
    100% {
        -webkit-transform: translateY(100%);
    }
}

我改变了你的makup和动画设置,现在符号不断下降,它们之间没有空格:

DEMO

html,body{height:100%;padding:0;margin:0;}
.wrap{position:relative;height:100%;overflow:hidden;}
.rainSec, .rain {
    font-size:2em;
    color:blue;
    width:1em;
    height:100%;
    position:absolute;
    left:0.5em;
    bottom:100%;
    overflow:hidden;
}
.rain{
    -webkit-animation: fadeInDown 8s infinite;
    animation: fadeInDown 8s infinite;
    -webkit-animation-timing-function: linear;
    animation-timing-function: linear;

}
.rainSec {
    -webkit-animation: fadeInDown 8s 2s infinite;
    animation: fadeInDown 8s 2s infinite;
    -webkit-animation-timing-function: linear;
    animation-timing-function: linear;
}


@-webkit-keyframes fadeInDown {
    0%   { -webkit-transform: translateY(0); }
    50% { -webkit-transform: translateY(200%); }
    50.1%{ -webkit-transform: translateY(0); }
    100% { -webkit-transform: translateY(200%); }
}
@-keyframes fadeInDown {
    0%   { -webkit-transform: translateY(0); }
    50% { -webkit-transform: translateY(200%); }
    50.1%{ -webkit-transform: translateY(0); }
    100% { -webkit-transform: translateY(200%); }
}

<div class="wrap">
    <p class='rain'>< $ " " 1 0 1 0 0 0 $ 1 0 2 ( { $ 1 0 = ) 0 1 0 0 0 1 }</p>
    <p class='rainSec'>< $ " " 1 0 1 0 0 0 $ 1 0 2 ( { $ 1 0 = ) 0 1 0 0 0 1 }</p>
</div>
