A typically single-colored [[background]] formed into a square grid by a series of thin lines.

The lines must be perpindicular or parallel with respect to each other, but [i]need not[/i] be with respect to the sides of the image; a square grid rotated by an angle is still a square grid.

Not to be confused with [[checkered background]], where squares are filled with two alternating colors, or [[border]], a line that runs along three to four edges of the image.
