Platform-agnostic style

Hello,

I am working on an hybrid for client that work in iOS and Android.
A designer has made all the screens’ design with a branded theme.

My concern is that in ionic, the style automatically adapt to the platform but I would like to be able to make a platform-agnostic SCSS theme that reflect the provided design.

Is there a way to override/desactive automatic platform theming?

Thanks

I know what SASS is and how to customize ionic style, but it does not answer my question…
