css - 将 CSS 动画与页面的其余部分隔离开来

标签 css animation spinner

我很高兴有一个 CSS 加载动画。有点问题，想知道是否有人知道解决方案。

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

我想把整个内容都涂黑，当动画达到最大尺寸时，黑屏就会消失。所以在加载时整个页面将是黑色的，当然除了动画。一旦动画达到最大尺寸，所有内容都会出现。

对此有什么想法吗？真的很感激任何事情。玩得开心，只需要完善一些东西。谢谢。

最佳答案

这是另一个更笼统的答案。

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:

  • 给每个元素一个特殊的类，比如 appear-later
  • 定义类 .appear-later { opacity: 0; }
  • 使用 jQuery，在计时器到期后，从拥有该类的元素中删除该类。
setTimeout(function () {
    $('.appear-later').removeClass('appear-later');
}, 2000);

此外，最好将 javascript 代码放在 html 标记之后。

Here's the pen

我使用 color: red 而不是 opacity: 0 以便更显眼。

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