在上面引用的文章中显示的代码示例中，当文档准备就绪时，有些东西会淡入淡出，但是您可以执行其他操作.请查看该库提供的效果:

I would advise to use jQuery. This will give you a good idea:

In the code samples shown in the article referenced above, something is fade in when the document is ready, but you can do something else. Please review the effects available with this library:

More complex effects can be created using any combination of CSS properties and the method .animate(). It will allow to modify any property values smoothly in an animated motion. Please see:
