The Magic Borders feature lets you set a snap zone on the edges of window or around the edge of the screen. A border snap zone consists of a specified number of pixels around the edge of the screen. Snap zones are measured in pixels. A window snap zone consists of a specified number of pixels around the edge of a window. Windows automatically snap together and line up side by side when you move one window into the snap zone of another window. Moving a window into a border snap zone automatically lines up the edge of the window with the edge of the screen.
