I'm not sure where to post a support questions so I'll try here and maybe someone can direct me? How can I set the background image to be fixed. right now it seems the page scrolls over the image separately and I want the to be fixed together. Also, how can I change the hover and active page colour in the top menu? Two more things- Is there a way I can remove all the navigation from showing on the slider (the arrows and the dots), as well as change the transition from slide to fade (if this is even possible)?
