4.7 - CSS Popup Image Viewer

[JohnBi]

Hello to everybody,
I am using the sample to implemeting my galleries. It works fine, however is there any way to show the popup image always at the center of the screen?
Infact, if I have an thum at the bottom of the page, the popup is out the screen.

Thanks and Regards
JohnBi

Hi to everybody,
I solved with this code:

.thumbnail:hover span{
visibility: visible;
width:500px;height:380px;
left:55%;top:50%;
margin:-200px 0 0 -450px;
border:1px solid #000;
position:fixed;
}
