How to make row background transparent

[wp_LayNerd]

Im not very skilled so pardon my ignorance..

I would like the credits (.png with white text on transparent background) scroll over the fixed video with the video still visible. But the black background of the row covers the video and making the row background color transparent (#ffffff) doesnt helb but only makey it white.

Did I miss somtething?

Anyway: Thanks a lot in advance!

.hascover #footer-region, .cover-content, .cover-region {
    background-color: transparent!important;
}
.cover-region-desktop.id-21 .cover-inner{
background-color: transparent!important;
}
#grid.id-21 .row{
background-color: transparent!important;
}

Enter this css in "lay options" -> "custom css & html" -> "custom css for desktop"

Now anotther issue emerged on the Mobile versions: On Firefox everything is black like its supposed to be, while on Safari/Chrome all the backgrounds appear white..
Any hint for a quick fix?

Ok, I solved the black/white issue..
Only the initial problem is still there in the mobile version and putting the code above into "Custom CSS for Phone" doesnt fix it. What do I need to change?

Thanks so much again!
