I am using the free Manifest theme with a custom CSS upgrade. I have not significantly altered anything in the css file, except adding a custom header. Yet, my customizing window shows me a much darker background color than on the actual site. The background there is a light green, where it should be a darker shade of that color. Why is that happening? I dug a little in the source code and found out that there are two conflicting background-color lines, are those causing harm? Why are they there in the first place? More importantly, why can I not add my own background color in the css file? It does not do anything.
Please help me.
