Hi, I’m dealing with black space that’s inserting in between my sections (that has white background color). Could anyone help me? I see no position nor margin/padding issues there.

These classes have a margin top which causes the black background of the body to show.

You could for example remove the margin verticle div and place a top-padding on the testimonial_component class!
