Question

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。

这就是动画当前的工作方式：http://www.wilsonschlamme.com/animation.html

我想整理整个内容，第二个动画达到最大尺寸，黑屏消失。所以在加载时，除了动画之外，整个页面都是黑色的。一旦动画达到最大尺寸，所有内容都会出现。

对此有何想法？真的很感激。玩得开心，只需要完善一些东西。感谢。

Answer 1

检查this。

最初我将身体背景设置为黑色。

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

计时器后，将其更改为透明/白色。

spawn

（您也可以使用CSS而不是js来完成此操作。）

Answer 2

这是另一个更一般的答案。

如果您想在动画结束前隐藏多个元素，然后显示它们，您可以执行以下操作：

为每个元素添加一个特殊的类，比如appear-later
定义课程.appear-later { opacity: 0; }
使用jQuery，在计时器到期后，从拥有它的元素中删除该类。

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

此外，最好将你的javascript代码放在html标记之后。

Here's the pen

我使用color: red代替opacity: 0以便更加明显。

此外，在Codepen中，您可以通过转到设置 - Javascript - 快速添加

来加载jQuery

从页面的其余部分隔离CSS动画
