I can't get magnific-popup animations to work

Question

I've been through the excellent documentation for this and it's great. http://dimsemenov.com/plugins/magnific-popup/documentation.html I have the basic pop up working fine.

My problem is with the animations. I just can't get them to work. Apologies if I've missed something very basic but I've spent too long on this now and hope someone can point out my mistake. It currently just appears no fade nothing.

I've played with it on codepen and can recreate the issue by removing the CSS so perhaps this is not getting through correctly, although I know it is linking as it is styling the pop up just not the animations.

Here is my html:

<div id="Column1"><div id="aboutus" >
<div id="pop" >

    <a href="/stalkseed/assets/Uploads/stalk-seed-about-us.jpg" data-effect="mfp-newspaper" title="" alt="" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('about-us','','/stalkseed/assets/Uploads/aboutus-ovr.jpg',1)"><img src="/stalkseed/assets/Uploads/aboutus.jpg" name="about-us" border="0" id="about-us"/></a>

</div>

My JavaScript from the same page:

    <script type="text/javascript">//<![CDATA[
$(document).ready(function() {
$('#pop').magnificPopup({
  delegate: 'a',
  type: 'image',
  removalDelay: 500, //delay removal by X to allow out-animation
  callbacks: {
    beforeOpen: function() {
      // just a hack that adds mfp-anim class to markup 
       this.st.image.markup = this.st.image.markup.replace('mfp-figure', 'mfp-figure mfp-with-anim');
       this.st.mainClass = this.st.el.attr('data-effect');
    }
  },
  closeOnContentClick: true,
  midClick: true // allow opening popup on middle mouse click. Always set it to true if you don't provide alternative source.

});});
//]]>
</script>

My CSS

Answer 1

In case anyone interested in the .mfp-move-from-top animation below is the code:

.mfp-move-from-top .mfp-content{
    vertical-align:bottom; 
}

.mfp-move-from-top .mfp-with-anim{
    opacity: 0;
    transition: all 0.2s;
    transform: translateY(-100px);
}

.mfp-move-from-top.mfp-bg {
    opacity: 0;
    transition: all 0.2
}

.mfp-move-from-top.mfp-ready .mfp-with-anim {

    opacity: 1;
    transform: translateY(0);
}

.mfp-move-from-top.mfp-bg.mfp-ready {
    opacity: 0.8;

}

.mfp-move-from-top.mfp-removing .mfp-with-anim {
    transform: translateY(-50px);
    opacity: 0;
}

.mfp-move-from-top.mfp-removing.mfp-bg {
    opacity: 0;
}

Answer 2

I ran into this same problem and after banging my head against all the hard surfaces in my office I discovered that I need to rename the css classes to match the fade example he provided here.

So for example the mfp-zoom-out animation:

.mfp-zoom-out .mfp-with-anim should be .mfp-zoom-out.mfp-bg

.mfp-zoom-out.mfp-bg stays the same

.mfp-zoom-out.mfp-ready .mfp-with-anim should be .mfp-zoom-out.mfp-ready .mfp-content

.mfp-zoom-out.mfp-ready.mfp-bg should be .mfp-zoom-out.mfp-bg.mfp-ready

.mfp-zoom-out.mfp-removing .mfp-with-anim should be .mfp-zoom-out.mfp-removing .mfp-content

.mfp-zoom-out.mfp-removing.mfp-bg should be .mfp-zoom-out.mfp-bg.mfp-removing

Answer 4

You can also make great use of animate.css (http://daneden.github.io/animate.css/). Once you initialize the popup make sure you add animate class along with the desired animation class from the library. For example animate fadeIn.

Answer 5

I had the same problem. found the solution here: just change

beforeOpen: function() {
    this.st.mainClass = this.st.el.attr('data-effect');
}
to this (adds a space and then the class, in case option is being used):

into

beforeOpen: function() {
    this.st.mainClass += ' ' + this.st.el.attr('data-effect');
}
