Set filter to layout PC Visu

[victor.back]

Hi.

I want to set a filter for one specific layout with the ID 1. I did'nt manage to do this in CSS, but I did manage to set every backgroud to my filter with this

Code:

/* Set style on every element*/
[style*="background-image"] {
  filter: grayscale(80%) brightness(50%) !important;
}

and but this on every widget that I dont want this filter to follow

Code:

/* reset style for widget with data-widget-id="35" */
#widget-35 {
  filter: none !important;

But I have to this on every widget and it gets a little anoying

How can I put this filter on only Layout ID 1?
