I want to create a responsive login screen, my screen has only three elements, an image in the middle and two more buttons, each element in a row of the "ionic grid" ... I would like to define a way to always keep the and the image in the middle of it regardless of the size of the "responsive" screen ... I thought of setting a number of rows, if it is possible to keep some empty rows serving as spacing to the elements of the screen. but I do not know how I'll do it, could anyone help me?
