Making arrows in content slider responsive

Hi,

I’ve changed the arrows in the content slider, so they look more like the arrows on i.e. the easy slider. I did this according to the guides in some of the support tickets, I found on you site.

But I can’t seem to get the arrows to show, when I visit the site from a mobile device (in this case a smartphone). Any ides as to what I can do to fix this?

Cheers
Malene
