Question

I’m trying to get the red div to come up and sit under the click me link when that link is clicked.

$('.clickMe').click(function() {

    var pos = $(this).offset().top;           

    $('.myDiv').animate({
        marginTop: '-'+pos+'px',
    }, 1000 );       

}); 

<a href="" class="clickMe">Click Me</a>
<br /><br /><br /><br /><br /><br /><br /><br />
<div style="position: absolute; border: 1px solid red; height: 50px; width: 50px" class="myDiv"></div>

Here’s my failed attempt:

How do I get this to work?

Answer 1

Try this instead, animating the top property is probably a better choice, negative margins can have undesirable effects:

$('.clickMe').click(function(e) {

    e.preventDefault();

    var pos = $(this).offset().top;           

    $('.myDiv').animate({
        top: pos + $(this).height()
    }, 1000 );

});
