Is it possible to modify the css of a standard lightning page for a sf object?
What I was thinking of is insert a custom component but would that component be able to find an element on the rest of the page that not inside of it?
Is there a different way?
I want to use
getElementsByClassName and rely on the class of a salesforce's element. I understand this is fragile and this class name can change at any time but this is the requirement I am working with.
