Extend description panel on Image Effect CK

I've added those to the existing css but it's not working for me?

figure.imageeffectck:hover .imageeffectck_image {height:600px{

extends the panel to a fixed height but I was wondering if their was a way this could automatically adjust the height of the div depending on the content?

I've tried adding overflow:auto but that doesn't work?

EDIT

figure.imageeffectck:hover .imageeffectck_img{height:600px;}

I have given your the code ...this is not what I have written

I've added the code you've supplied to the css but it hasn't worked?

Check the "USERS" panel at

I've extended the list to include more items but they remain hidden

figure.effectck-sarahPink img, figure.effectck-sarahBlue img {
max-width: none !important;
width: -webkit-calc(100% + 20px);
width: calc(100% + 20px);
-webkit-transition: opacity 0.35s, -webkit-transform 0.35s;
transition: opacity 0.35s, transform 0.35s;
-webkit-transform: translate3d(-10px,0,0);
transform: translate3d(-10px,0,0);
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
min-height: 220px;
object-fit: cover;
}

you must adapt the min-height value to your need, of course if you add then more text, you will get the same ...
may be that you must not put so much text
