I'm trying to implement react-trello in an Ionic app and all I want that the main container has on the top 57px margin and on the bottom also so the whole trello app should have a top/bottom 57px margin how would I do this because all styles I tried are ignored?

I did everything from margin/padding to top/bottom everything also with !important but no effect.
