I am trying to format a button in tersus with css. I have already declined the html.styleClass and the html.tag. Changes like font-size and color work very well, but I can't get the button in the middle of the screen. I have used the attribut margin, but it works only horizontally. Vertical specifications affect nothing at all. The button seems to be attached to the top of the screen. Can you please help. thanks in advance.
