Changing background color does not change across full screen width

Hi,

Nice plugin! But… the default background color is pale yellow which doesn’t go with my site color. I successfully changed the background color, but about an inch on both left and right sides remain the default color. It’s not changing the color across full screen width which looks silly and unprofessional. Max width is set at 100%. Any idea how to correct this?

Secondly, my theme has a border, so ideally I would only want background color (white) to extend to the border, leaving the border color on sides of sticky menu. Again, it’s a matter of looking professional.

Lastly, anyway to get menu to stick without “transition” to sticky? Just scrolling and it sticks immediately, seamlessly?

Thanks.
