ShowContents
• ShowContents is an option for cells that determines if an object represented by a StyleBox should be displayed on the screen or replaced by blank space.
• With the setting ShowContents 
False, any StyleBox object is not displayed on the screen. It is replaced by an amount of blank space equal to the width of the expression. This feature is useful for adding blank space of an exact length, such as for aligning text appearing on successive lines of a cell.
• With the default setting ShowContents True, a StyleBox object is displayed on the screen like any other input.
