Thank you for the last idea too.
I will see about making this another option as well since the background image still includes the grey borders.
It worked! I tried it both ways with a simple code like black so now it’ll just be finding another color that also works.
Thank you so much.
PS I’m on Firefox but that’s good to know it works in IE too.
Thank you for the clarification.
I want to change the gray – to something more colorful than white or black (like a light orange)
I did leave the image alone when I tried to change the hex codes but perhaps I’m using the wrong codes.
