Conditional Formatting for Lists

Hello, I am trying to build a conditional formatting for a due date. I would like it red for overdue (past today's date), "sp-css-backgroundColor-errorBackground" for dates within 30 days of today, and "sp-css-backgroundColor-warningBackground" for dates within 60 days of today.  Could someone help me with JSON that I can import into Lists on Teams (should be the same as lists on Sharepoint)?

I'm not familiar with the composition and options for JSON fields relative to Microsoft. I'd also appreciate documentation so I can solve my own problems like this in the future. 

Thanks in advance!

Here is the template code provided (doesn't match my conditions):

    "padding": "0 2px"
