The “correct way” would be to create a new theme.css in
C:\Program Files\Inductive Automation\Ignition\data\modules\com.inductiveautomation.perspective\themes
which would import the light.css theme (or whatever theme you are using)
and than under that you could put the above css selectors.
However its rather bothersome so i’ve found you can css inject into style classes.
By wrapping whatever css you have in }{ and put it in the background image.
This is kinda a bug in igntion tho, which might get fixed but i doubt it as it posses no vulnerabilities.
