How to find and reuse the CSS template (that is used to render the local browser page)

Thank you for the great work! Since I started to use AW last year, it has been creating more and more positive impact on my life.

I am worndering if there is a way to find & reuse the css template that is used to render my local AW page.

I am trying to incorporate the views of AW data somewhere. It would be nice if the views could keep a consistent appearance by following the same css setting. But I didn’t find css information in the document.
