Would like to move button on Popup Pro

I would like to move the "click here" button in the Cabriolet appearance from the left to the right hand side of the pop up, what custom CSS code would I use for that?

Also if I would like to change the Link color in the PopUp and tried
#popup .wdpu-a {color: #E9A825;}
But this does not work :slight_frown:
could you please help me out here?
