Reverse Queryselector

[Aykut akguen]

So I wanted to ask if its possible to get all style objects which get applied to an element, right now i have a solution though a single variable where i reset it of each element until the variable field is empty, but that requires for each style affecting it a redraw which is bad, so i was curious if there is a reverse way to get all style objects applying to my elements, ( i create the styles over js so i have full controll) Does anyone know a solution? I asked everywhere before asking people, who code chromium itself.
