Lovelace CSS formatting references?

Configuration Frontend

Is there a list somewhere of all the formatting options we can use in Lovelace?

Specifically i would like to:

  1. Using the picture-elements ane a state-label wrap text or align left/right/Center.
  2. change the size of a state-icon that has an svg file using entity_picture

I’ve tried the typical css tags and it seems to have no effect. And to change the icon size in the state-icon I found through the forum it’s —iron-icon-height and not through the height and width tags like one would expect.

Found this
But i’m still searching how to add custom CSS as the list above doesn’t allow for complete control over the Style.
