Animation Css Vs Ionic

I am aiming to add some animation into my project.

Is there any difference if animation was done via CSS compared to Ionic animation method?

Did you found this out already? I’m asking myself the same question. I am developing with css animation, but I feel like it’s not that smooth. I thought about getting them outside the ngZone, but I really don’t know how to make them smoother. I don’t understand why they aren’t in the first place.
