Jquery weird effect with fadeIn()

Question

When i click on that link, i want to append and fadeIn another element.

Problem is that the element fades in, very fast fades out and after that fades in back.

You can see here : http://jsfiddle.net/yfae3y11/1/

HTML

<div id="boxpms">
   <a class="pms" href="#" title="0 messages" >click
   <span id='pms_number' >0</span></a>
</div>

jquery

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

$('<div id=\'messages_box\'><ul><li>test</li></ul></div>').hide().appendTo('#boxpms').fadeIn('slow');
e.preventDefault();                     

});

css included in fiddle.

How can i make a nice fadeIn without that effect?

Answer 1

That's because of CSS transitions used together with jQuery effects.

Removing this part of the CSS styles, solves the issue:

-webkit-transition: 0.2s ease-out;
-moz-transition: 0.2s ease-out;
-o-transition: 0.2s ease-out;
transition: 0.2s ease-out;
-webkit-transition-property: opacity, padding, visibility;
-moz-transition-property: opacity, padding, visibility;
-o-transition-property: opacity, padding, visibility;
transition-property: opacity, padding, visibility;
