Disable Ionic styles completely

I’m new to the Ionic/Cordova/Angular scene and am planning to make a completely custom UI application for both desktop and mobile. I want the UI to be consistent across all platforms (more like a responsive website) and so I feel the Ionic UI and components aren’t really a good fit for what I’m going for. However, I don’t really have enough in-depth knowledge yet to set up Cordova and Angular together on my own and in an optimised way, and so Ionic seems like the logical choice.

It’s a shame Ionic is so tightly coupled to the UI but maybe this will change in the future. For now, what is the best course of action to completely exclude the Ionic styles so that I can just use Bootstrap as a base instead?

Also if you have any other, better suggestions for me, I’d be happy to hear them.
