White space, also known as negative space, is the term describing open space between design elements. It is essential for providing spatial relationships between visual items and actually guides your reader's eye from one point to another.
White space is an important layout technique often overlooked by the inexperienced designer.
While some artists concentrate heavily on what to put in, they overlook what to leave out. An appealing design must also be easy on the eyes. Without adequate white space, text would be unreadable, graphics would lose their emphasis, and there would be no balance between the elements on a page. White space provides our brains with much-needed breathing room to absorb the material displayed before us. Treat white space as more than just background.
