Lightbox Preloader ?

Hi there, im just designing my new website and would like to have a full screen preloader page with a line of text and a gif, now the best way to do this is using a full screen light box because I also want to hide the header.
I tried using the wix code for opening and closing a preloader but I have no idea what im doing with code and with a light box the code does not close it like with a strip because the lightbox still uses the click to close function.
Could anyone please help me out, is there any copy and paste code or tutorial on how I can use a code to open then light box and then close it completely once the loading is done.
Any help would be greatly appreciated thanks so much! :slight_smile:

I’ve got that problem too!
