Gray background in page layout
It might seem a silly question, but what does the gray background in page layout mean? I know that is where an image is suppose to go, but, for example in applying page layouts in the “Introduction” in options 5 and 6, there is a different option I need, that is a white background and a title. Option 6 has the white background but does not give the alternative of having a title. Option 5 is what I need but it has a gray background that I suppose is telling me an image goes there. What if I do not add an image? Will it take the color background I have been using in other pages or will it take a white background?
