我注意到一个简单的事情，同时看着Windows 8加载屏幕的屏幕，有一个preloader（或加载图标），这是相当有趣的，它有一点重力/摆动效应。我想用javascript和css复制相同的内容，但我对javascript动画没有太多的了解，因此想知道是否可以给我一个方向，我可以找到类似的例子。您也可以通过提供具有类似动画类型的代码片段来提供帮助。Windows 8 preloader（加载图标）使用HTML5和JavaScript没有图像
任何帮助，将不胜感激。
查询网站CSSload。在这里，您可以在几秒钟内制作CSS加载器。我制作了Windows 8加载程序，因此您可以看到它here。
@keyframes orbit {
0% {
opacity: 1;
z-index:99;
transform: rotate(180deg);
animation-timing-function: ease-out;
}
7% {
opacity: 1;
transform: rotate(300deg);
animation-timing-function: linear;
origin:0%;
}
30% {
opacity: 1;
transform:rotate(410deg);
animation-timing-function: ease-in-out;
origin:7%;
}
39% {
opacity: 1;
transform: rotate(645deg);
animation-timing-function: linear;
origin:30%;
}
70% {
opacity: 1;
transform: rotate(770deg);
animation-timing-function: ease-out;
origin:39%;
}
75% {
opacity: 1;
transform: rotate(900deg);
animation-timing-function: ease-out;
origin:70%;
}
76% {
opacity: 0;
transform:rotate(900deg);
}
100% {
opacity: 0;
transform: rotate(900deg);
}
}
或者，尝试this code example ...
这真的很酷的人，正是我所期待的！ thx :) – RynoRn 2012-11-09 12:54:52

在涉及DOM操作的脚本执行期间，动画GIF可能在单线程JavaScript环境中停顿，因此硬件启用的CSS3动画在我看来表现得更好。我更新了JSFiddle以消除无关的cssload.net生成的标记，方法是删除子wInnerBall类div，然后将它们渲染为：在伪元素CSS之后，删除wBall ID并通过第n个子选择器设计la Jan Rubio的代码示例。 [链接]（http://jsfiddle.net/nPQNH/48/） – TaeKwonJoe 2013-05-24 00:23:38
不知道的JavaScript，但你可以从http://preloaders.net/en/search/windows8
下载，我不知道，但也许这就是你想要的东西：
<progress style="color: white;" class="win-medium win-ring"></progress>
我发现，你可以找到关于C:\Windows\WinStore\WinStore.css和WinStore.htm一个类似的脚本，只需打开Winstore.htm，你会发现一个类似环加载动画，由IE10提供，如果只有人可能会抛售从Windows Shell中的动画信息...如果你用记事本看WinStore.css，你会看到这样的事情：
splashProgress::-ms-fill
{
animation-name: **-ms-ring**;
}
这个变量是一个动画信息存储在Windows Shell的某处吗？
我测试了在Chrome和Firefox中加载HTML页面，没有什么，只是一个正常的加载栏。
对不起，我的英语不好。我来自阿根廷。
Metro上的某些样式过程如'-ms-ring'和'html：-ms-lang（ar，dv，fa，he，ku-Arab，pa-Arab，prs，ps，sd-Arab，syr ，ug，ur，qps-plocm）'。他们只是为了窗户和窗户来处理它们！ – 2013-01-19 17:58:28
这里是我的纯CSS3实现与没有使用Javascript中，我结合CSSload和Jan Rubio's codepen技术最小标记和没有ID选择：

这是CSS3中另一个关于Modern UI ProgressRing动画的内容。它基于已经提到的Jan Rubio的solution，并进行了一些调整（尽管如此，仍然需要调整）。
关注the live example或者使用下面的代码，如果codepen不可用：
HTML
<div class='progress-ring'>
<div class='progress-ring__wrap'>
<div class='progress-ring__circle'></div>
</div>
<div class='progress-ring__wrap'>
<div class='progress-ring__circle'></div>
</div>
<div class='progress-ring__wrap'>
<div class='progress-ring__circle'></div>
</div>
<div class='progress-ring__wrap'>
<div class='progress-ring__circle'></div>
</div>
<div class='progress-ring__wrap'>
<div class='progress-ring__circle'></div>
</div>
</div>

谢谢@coder，我会通过这个尝试去实现重力效应...... – manishekhawat 2012-04-28 16:10:03
