页面加载时的 CSS3 滑出动画

Question

我试图在页面加载时使用纯 CSS 使图像向左滑出。

到目前为止，我已经得到:http://jsfiddle.net/o7thwd/qZbhJ/这似乎有效。我似乎无法解决的问题是动画结束后图像如何重新回到 View 中。

#slide {
    left:0;
    width:268px;    
    -moz-animation-name: slideOut;
    -moz-animation-iteration-count: once;
    -moz-animation-timing-function: ease-out;
    -moz-animation-duration: 1.5s;
    -webkit-animation-name: slideOut;
    -webkit-animation-iteration-count: once;
    -webkit-animation-timing-function: ease-out;
    -webkit-animation-duration: 1.5s;
    -o-animation-name: slideOut;
    -o-animation-iteration-count: once;
    -o-animation-timing-function: ease-out;
    -o-animation-duration: 1.5s;
    animation-name: slideOut;
    animation-iteration-count: once;
    animation-timing-function: ease-out;
    animation-duration: 1.5s; 
}
@-o-keyframes slideOut {
    0% {
        margin-left: 0;
    }
    100% {
        margin-left: -268px;
    }
}
@keyframes slideOut {
    0% {
        margin-left: 0;
    }
    100% {
        margin-left: -268px;
    }
}
@-moz-keyframes slideOut {
    0% {
        margin-left: 0;
    }
    100% {
        margin-left: -268px;
    }
}
@-webkit-keyframes slideOut {
    0% {
        margin-left: 0;
    }
    100% {
        margin-left: -268px;
    }
}

如何让它像初始页面加载时那样保持向左折叠？

Answer 1

基本上，您添加以下 CSS -webkit-animation-fill-mode:forwards; 并且动画结束将是持久的，而不是恢复到原始状态。

哦，您只需要使用特定于动画的 -webkit- 供应商，没有 -moz- 或 -o- 供应商动画细节

CSS:

#slide {
    left:0;
    width:268px;    
    -webkit-animation-name: slideOut;
    -webkit-animation-iteration-count: once;
    -webkit-animation-timing-function: ease-out;
    -webkit-animation-duration: 1.5s;   
    animation-name: slideOut;
    animation-iteration-count: once;
    animation-timing-function: ease-out;
    animation-duration: 1.5s;
    -webkit-animation-fill-mode: forwards;
    animation-fill-mode: forwards;
}

@keyframes slideOut {
    0% {
        margin-left: 0;
    }
    100% {
        margin-left: -268px;
    }
}

@-webkit-keyframes slideOut {
    0% {
        left: 0;
    }
    100% {
        left: -268px;
    }
}
