CSS for change loader background

[PeopleInside]

Hi,
I created some custom CSS for have the Dark Mode active.

Is not looks really very professional but is a small solution to have a small dark theme active if Windows is dark.
When page load a white background still be showed, can you telling me what is the CSS name of that background loader (white transparent) so I can add to the dark mode rule to use a darker transparent loading background?

Thank you!

Seems I'm simply ignored, no answer here and no answer on the forum.
I'm asking if I made something wrong to you. I see replies in the forum to users while my topic seems still be ignored.
OK... I take note of it and I am sorry for it.

Found, this is the CSS that allow to change loader background color:

.uv-loader-view {
	background: rgba(98, 145, 150, 0.79);
}

This CSS code should be added to the file uvdesk/public/bundles/uvdeskcoreframework/css/_uikit.css
in the section you have also to add

@media (prefers-color-scheme: dark) {
}

So the full code to change background when system are in dark mode are:

@media (prefers-color-scheme: dark) {
.uv-loader-view {
	background: rgba(98, 145, 150, 0.79);
}
}

The solution I found works only for operator side, not for the loading user side.
