Animate of pseudo elements using jQuery

I'm using a:after, it contains right: Ypx.

I want to use animate method in jQuery to move the element (a:after) from Ypx to Zpx, how can I do it?

For example:

[link-text][after]
[link-text]-- moving > --[after]

I know how to do it without animation, just doing a:hover:after { right: Zpx } but how with animation?

Use next() instead. Here's how you can achieve exactly that.

What you are trying to do is extremely hacky and I'd strongly recommend you to put make real elements instead of trying to animate pseudo-elements. However, for future reference: the only way of animating a pseudo-element is by inserting a style tag and changing the value in actual CSS, such as...

var styles = document.getElementById("pseudo-mover")
var distance = 100;

var move = function(){
    styles.innerHTML = ".box:after {left: " + distance + "px}";
    distance++;
    if (distance < 200) 
        setTimeout(move, 30);    
}

move()

This is vanilla js, but you could use the step callback in jquery's animate to hook in to jquery's easing and timing functions.

You can use CSS3 transitions to accomplish this, but sadly they are only supported (as far as I know) in FireFox 4+ right now.

http://jsfiddle.net/XT6qJ/1/

#foo:after{
    content:'!';
    display:inline-block;
    border:solid 1px #f00;
    padding:3px;
    width:25px;
    text-align:center;
    -webkit-transition:margin-left 1s;
    -moz-transition:margin-left 1s;    
    -ms-transition:margin-left 1s;
    -o-transition:margin-left 1s;    
    transition:margin-left 1s;    
}
#foo:hover:after{
    margin-left:100px;    
}
