使用HTML5和javascript（不带图像）的Windows 8预加载程序（加载图标）

我注意到一件简单的事情，当我看Windows8加载屏幕的时候，有一个预加载程序（或加载图标），这很有趣，它有一点重力/摆动效果。我想用javascript和css复制相同的动画，但是我对javascript动画没有太多的了解，因此我想知道你是否能给我一个方向，在那里我可以找到类似的例子。您还可以通过提供具有类似动画的代码片段来提供帮助

任何帮助都将不胜感激

不确定javascript，但您可以从下载它，我不确定，但可能这就是您想要的：

<progress style="color: white;" class="win-medium win-ring"></progress>

查看网站。在这里，您可以在几秒钟内完成CSS加载程序。我制作了Windows8加载程序，所以你可以看到它

或者，试试…

我发现你可以在

C:\Windows\WinStore\WinStore.css

和

WinStore.htm

上找到一个类似的脚本，只要打开

WinStore.htm

，你就会发现一个类似的环加载动画，由

IE10

提供，只要有人可以从Windows Shell中转储动画信息。。。如果您使用记事本看到

WinStore.css

，您将看到如下内容：

splashProgress::-ms-fill
{
    animation-name: **-ms-ring**;
}

该变量是否是存储在Windows外壳中某处的动画信息

我测试了在Chrome和Firefox中加载HTML页面，没有什么，只是一个普通的加载条

对不起，我的英语不好。我来自阿根廷。

这是我的纯CSS3实现，没有Javascript，我结合了最小标记和无id选择器的技术：

下面是CSS3中现代UI ProgressRing动画的另一个例子。它是基于已经提到的简·卢比奥（Jan Rubio）的，并进行了一些调整（尽管仍需要调整）

如果代码笔不可用，请观看或使用以下代码：

你已经检查过这一个了吗？现在我可以找到这两个，你可以从这里开始：谢谢@coder，我将通过这一点，并将尝试实现重力效应…这一个使用CSS3检查我的答案！我更新它。。。现在，您可以创建预加载只使用CSS与简单的工具：）这真的很酷的人，正是我所寻找的！thx:）在涉及DOM操作的脚本执行过程中，动画GIF可能会在单线程Javascript环境中暂停，因此在我看来，支持硬件的CSS3动画的性能要好得多。我更新了您的JSFIDLE以消除无关的cssload.net生成的标记，方法是删除子WinneBall类div，而是使用：after伪元素CSS呈现它们，删除wBall ID，并使用n个子选择器对它们进行样式化la Jan Rubio的codepen示例。CSS动画也不会像8位透明GIF一样被难看的哑光颜色所困扰。@TaeKwonJoe，你说得对！但我对你们分享的正确例子有疑问。只有一个动画点。我看不到其他人。感谢您分享更好的解决方案！：）@Vukaš在哪种浏览器中只显示一个点？我刚刚用Firefox 12.0、Chrome 28.0.1500.52和IE 10.0.9200.16599进行了双重检查，所有5个点都正确渲染。Metro上处理的一些样式，如

-ms-ring

和

html:-ms-lang（ar、dv、fa、he、ku-Arab、pa-Arab、prs、ps、sd-Arab、syr、ug、ur、qps-plocm）

。它们只适用于windows和windows处理它们！

splashProgress::-ms-fill
{
    animation-name: **-ms-ring**;
}
