Go to the Field Set Styles section and create a style for all fieldset elements that removes the field set border, sets the width to 60%, and sets the top/bottom margin to 10 pixels and the left/ right margin to 0 pixels. For every field set legend, create a style rule that sets the background color to rgb(232, 232, 232), sets the width to 100%, and sets the top/bottom margin to 2 pixels and the left/right margin to 0 pixels.
