Problem with my gallery page

Hi,

I have a gallery page on my website (http://ca4u.com.br/home/?page_id=368) and when i click on an image, it opens fine but my menu, my logo and my contact phone are visible and over the image.
How can i change it so when i open the image everythings turns dark and only the picture stay visible?

Observation: It only happens in smaller monitors, like notebook monitors, 17 inch monitors. When i see this on monitors with more than 20 inches it works fine. On tablet and phones its fine too.

Sample screenshot attached.

 

Hello,

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

div.pp_pic_holder{
z-index:99999;
}

This will solve your issue.

 

Thanks a lot!
