[Plugin: Promotion Slider] Align slider to middle of page

Hi,

My slider doesn’t centrate in the middel of the page. So if you look at the columns underneath, i have 4 mm on the left and 10 mm and the right.

Is there any code (besides align=”center” that doesn’t work) i can put in my html code or in preferences or so to put the slider in the middle of the page?
