Can’t move the Submit button

Apart from putting this code (float: right) in to the DIV of the form layout I can not get the SUBMIT button to move to the right.
Now yes to some degree this solves the problem. Until you edit the form in anyway then you have to do a whole lot of sh?t to reset it for the updates to be applied.
So I wanted to put it in the CSS of the theme I’m using.
But it does not work, WHY?
EG: the code I’m entering it on and I’m assuming it’s the right one, is below with the “float: right”.
I have even tried using the “!important” but no go. Please advise?
