Set CSS Property per JS

[Karmalakas]

Most likely related and probably confirms it doesn’t work.

Is it possible to get CSS custom property with JS?

So I’ve tried to get custom prop in a bunch of variations of getComputedStyle(document.querySelector(":root")).getPropertyValue("--uxp-host-text-color") getComputedStyle(document.documentElement).getPropertyValue("--uxp-label-color") // ... No luck - I always get an empty string. Does UXP support that at all? As a workaround I get the theme with batchPlay, but I have no idea what actual colors are depending on the themes

Not sure, but I think you could play with your own custom props, but not default Ps CSS props
