How to set a button to the bottom of a slide

Hello guys,

I am pretty new with Ionic, I have been studying for two weeks.

I am building a form with slides, then in some pages I have a button and its position should be on the bottom of the page.

I tried to set ion-slide to “height: auto” and set the button to “position: fixed” and “bottom: 0”, but I believe it’s not the right way.
