Question

我创造了一个小提琴，但我不认为它显示正确。 http://jsfiddle.net/kVNQb/但无论如何都要查看代码可能会有用。

我正在使用CSS动画从此网站http://cssdeck.com/labs/css3-snow

创建雪

我想要做的是设置一个背景图像，然后在其上方设置雪的动画。目前我失去了动画雪或背景图像。

我是否需要创建一个ID并将我想要的图像设置为背景？

HTML代码

在这种情况下，技巧是在div和动画帧中将background-color设置为透明。小提琴：http://jsfiddle.net/f92gB/

HTML：

<body>
    <div id="container"></div>
</body>

CSS：

* {
    margin: 0;
    padding: 0;
}

a {
    color: white;
    font-style: italic;
}

/*Keyframes*/

@keyframes snow { 
    0% { background-position: 0px 0px, 0px 0px, 0px 0px }

    100% { background-position: 500px 1000px, 400px 400px, 300px 300px }
}

@-moz-keyframes snow { 
    0% { background-position: 0px 0px, 0px 0px, 0px 0px }

    100% { background-position: 500px 1000px, 400px 400px, 300px 300px }
}

@-webkit-keyframes snow { 
    0% { background-position: 0px 0px, 0px 0px, 0px 0px }

    50% { background-color: transparent }

    100% {
        background-position: 500px 1000px, 400px 400px, 300px 300px;
        background-color: transparent;
    }
}

@-ms-keyframes snow { 
    0% { background-position: 0px 0px, 0px 0px, 0px 0px }

    100% { background-position: 500px 1000px, 400px 400px, 300px 300px }
}

body {
    background-image: url("http://s17.postimg.org/9htu61zjj/background.jpg");
    background-size: cover;
    height: 500px;

}

#container {
    height:500px;
    margin: 0;
    text-align: center;
    color: white;
    font: 100px/1 'Spirax', cursive;
