Slicer Card Formatting on Black theme

Hey Krish_nidar ,

I don't think it is possible to get rid of the white rectangle box at present since there is no control in the slicer settings to explicitly control it. It gets a little less prominent when the background of the values is set as dark/black but it is never completely off. So yeah, I think you will need to design around this limitation. You could manually add thin dark shapes that are only wide enough to cover the white spaces and group them but that is too much manual effort.

Hope it helps!
