Promoted Links Dialog Pop Up Size

I am using Promoted Links with launch behavior = "Dialog" I manage to change the Dialog size by adding a Content Editor into my Main page with the following code .ms-dlgContent { width:1500px !important; height:1000px !important } .ms-dlgBorder { width:1500px !important; height:1000px !important }

The Dialog width and height did increase, however the Content itself seems to be in a fix width with scroll bars. How can I also have my Dialog contents width and height to increase? Many Thanks in advance.
