Extend description panel on Image Effect CK

I've tried a few but I can't seem to target the panel just in it's hover state?

Could you point me in the right direction for the class? i.e. figure.imageeffectck:hover ?

give me the url of your page to check that

The website is in development but you can check out how the Image Effect is being used here -

As you can see on the image hover I am wanting to show a list of information but currently am limited to around 5 items but potentially they might need 12 items.

you can try something like

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;}
