beginners questions serie: background page and lightbox should be fixed position

Hello Cedric,
I am considering Mediabox-CK for my new website and I am testing with the non-Pro version.

Is it possible to fix the position of lightbox and also the position of the webpage under the overlay of the lightbox? Of course the lightbox will open with its box centered. But if the user does scroll, then the lightbox complete with the underlying content of the webpage does move.

How can I achieve this?

Hi
if you want the popup to be fixed, you can add this custom css code to your page (in your template for example) CEd

I have tried as you proposed. But I have to change the top value to 25% in order to get the lightbox with video and the HTML content near to vertical centered position. But with audio, this doesn't work and the controls graphics are far too high within the page on desktop and on mobile / smartphone, the controls are near the bottom.

How can I achieve a fixed and also always vertical centered position?

Further, I would like the content of the webpage to be fixed also during the time, the lightbox is shown. Is this possible? – I have YOOtheme running on my website and their modal function does work like this. (But they have a lot other unacceptable flaws concerning lightbox and modalbox. That's why I am very interested in your Mediabox-CK)

give me the url of your page so that I can check

you can try also this css code

the content of the webpage to be fixed also during the time, the lightbox is shown. Is this possible?

this needs some JS code to be done... I can not give you an easy solution for that
I note your request on my list, I will check if I can add this option
