一个CSS3 动画执行完成后的问题...

Question

例:

在执行完一段css3动画后需要隐藏这个元素如何操作？也就是让它不重复动作.

使用animation参数forwards无效.

注：前提是不使用jQuery情况下能做到么？

Answer 1

To hide this, you can set opacity: 0

We can set the default opacity=0 for an element

Put the animation on each class, and then assign this class to this attribute

@keyframes ani{
    0%{opacity: 1}//此处显示转换为1 动画结束后就会自动隐藏了，因为元素的opacity为0，应该使用 display也可以，但我没用过，因为display没有动画效果
}

Answer 2

Is JavaScript acceptable without jQUery?

Depending on different types, two types of events will be triggered during animation playback:
1. AnimationEvent
2. TransitionEvent

The two implementations of the animation end event are:
1. animationend
2. transitionend

The Demo page is here, only Chrome has been tested:

For big compatibility pitfalls, you can see this part of the source code of AngularUI

Answer 3

You can use js timer. Just set the timer time to be the same as the css animation time
