Q:

The 'slow' animation speed is not working

I have an animation, but it always runs fast, despite having 'slow', I have tried integers too, but they still have no affect. I tested similar animation on other elements, and they react to slow.
THE ANIMATION
$('#customers_delete_link').click(function(){ 
    $('#customers_delete_link_anim').animate(
        {'width': '200px'},'slow', function() {
            $('#customers_delete_popup').fadeOut();
            hide_check_toolbar();
        }
    );
});

// HTML
        <div id="customers_delete_link_cont">
            <div id="customers_delete_link">Delete Prospects</div>
            <div id="customers_delete_link_anim"></div>
        </div>

What am I doing wrong here?

A:

You can use {duration: 5000} instead of 'slow':
$('#customers_delete_link').click(function(){ 
   $('#customers_delete_link_anim').animate(
        {width: '200px'},{duration: 5000}, function() {
            $('#customers_delete_popup').fadeOut();
            hide_check_toolbar();
        }
    );
});`

Change the duration value to change speed
