# Background

 Backgroundis an option that specifies what background color to use.
• The setting for Background can be any color or opacity specification.
• When an object has option Background->color, the specified color will normally be used as a background throughout the region defined by the object.
• Style specifies that color should be used as the background only for the region defined by the bounding box of expr.
• In constructs such as Grid, Item can be used to specify that a background should fill the complete region for a particular item.
• In a cell, the background is used only for the region inside any cell frame.
• Background->None specifies that no background should be used, so that in effect the background is transparent.
• Background specifies a background that follows the system appearance for the particular object or window used. For Inset, Background specifies that the background should be taken from the graphic in which it appears.
• For objects such as Grid, Column, and Row, the setting for Background can be a list that specifies backgrounds for individual columns, rows or elements.
