CSS - prevent :hover during animation?

问题:

I have a <div> that plays an animation. I want to prevent div:hover from taking effect on that <div> while the animation is still playing.

For example:

<div></div>

div:before {
    content: "A";
    -webkit-animation: A 5s;
    -moz-animation:    A 5s;
    animation:         A 5s;
}

@-webkit-keyframes A {
     100% { font-size: 5em; }
}

@-moz-keyframes A {
     100% { font-size: 5em; }
}

@keyframes A {
    100% { font-size: 5em; }
}

div:hover:before { 
    content: "B";
}

In this example, the animation increases the size of the letter "A". But if you hover the animation, div:hover changes it to letter "B". I would like to stop this from happening - in other words, if hovered it should still remain the letter "A" until the animation is finished. How should this be done in CSS?

You can do this with Jquery if you don't mind. For transition:

$("#YourDivID").bind("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){change div content to B});

For annimation:

$("#YourDivID").bind("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd", function(){change div content});

You can also just use pure js:

element.addEventListener("webkitAnimationEnd", callfunction,false);
element.addEventListener("animationend", callfunction,false);
element.addEventListener("oanimationend", callfunction,false);
