Questions :

  1. Is there any ionic class? that I can call and put the button right side without writing any CSS by myself
    [ a special note : if u want to talk about 12 columns system , then answer me : How can i put the button to the end of 5th column? ]

  2. Is there any way to use CSS utility in a way that : the button will be on right side no matter what the screen size is?
    [sometimes, in small screen, my button is just gone from screen - that means too much right side, how to avoid that : I want to preserve responsiveness ]

here is docs that has everything that you need
