Fotorama transparent background

Question

I'm using the Fotorama slider plugin, where you can open an image in fullscreen. I need the background to be transparent, but I can't seem to change it.

You can see what I mean by clicking on this link and open one of the images in the small slider in full screen.

I have tried to change all background in the slider to the following:

background: rgba{0,0,0,0);

Answer 1

It is possible - I figured it out myself with the following code:

.fullscreen .fotorama--fullscreen {
    background: transparent !important;
}

.fullscreen .fotorama__wrap {
    background: rgba(0,0,0,0.7) !important;
}

.fullscreen .fotorama__img {
    top: 0px !important;
    width: 50% !important;
    height: auto !important;
    margin: auto !important;
    left: 0px !important;
}
