从页面的其余部分隔离CSS动画

有一个CSS加载动画工作，我很高兴。有一点问题，想知道是否有人知道解决方案。从页面的其余部分隔离CSS动画

这是动画是如何工作目前：http://www.wilsonschlamme.com/animation.html

我想黑掉整个内容，第二个动画已达到最大规模，黑屏消失。所以加载后整个页面将是黑色的，除了动画当然。一旦动画达到最大尺寸，就会出现所有内容。

对此有何看法？真的很感激任何事情。玩这个，只需要完善一些东西。谢谢。

更好的答案，正确缩进代码，并尝试提供的jsfiddle。 – jack

这是另一个更一般的答案。

如果您想先隐藏多个元素，直到动画结束了，然后告诉他们，你可以做到以下几点：

给每个这些元素的特殊类的，说appear-later
定义类.appear-later { opacity: 0; }
使用jQuery，在计时器到期后，从拥有它的元素中移除该类。

setTimeout(function() { 
    $('.appear-later').removeClass('appear-later'); 
}, 2000);

而且，最好是把你的JavaScript代码的HTML标记之后。

Here's the pen

我为了用color: red代替opacity: 0更加明显。使用Javascript - -

此外，在Codepen，您可以进入设置加载jQuery的快速增加

嘿，这是一个非常有创意的解决方案！做得很好！非常感谢您的帮助先生。 – Masteryogurt

不客气:) – jack

检查this。

最初我将身体背景设置为黑色。

body { background: black; }

在您的计时器后，将其更改为透明/白色。

setTimeout(function() {document.body.style.background = "transparent";}, 2300);

（你也可以通过使用CSS来代替js）。

嘿，太棒了！谢谢@mikele。有一件事，你知道我是如何设置背景颜色来得到....更高的z-index？如果我有任何字体或任何其他颜色（黑色以外的颜色），则在动画结束之前仍会出现问题。 – Masteryogurt

你不能那样做。请给我看看jsfiddle或fork我的codepen，以便我可以尝试从那里修复它。 – jack

一种解决方法是给这些非黑色元素提供一个类，'.black {color：black！重要;}'，然后在上面的'setTimeout（）'中，添加代码从所有这些元素中移除该类。使用jQuery，它看起来像这样：'setTimeout（function（）{document.body.style.background =“transparent”; $（'。black'）。removeClass（'black'）;}，2300）;' – jack
