Grid may refer to any of the following:
1. A grid is a structure of intersecting lines or bars. It is used as a guide to divide and organize a space. Usually, a grid is two-dimensional, and the lines are evenly spaced, intersecting at right angles.
Grids are useful for organizing and ordering information. When information is organized in a grid structure, any unit of information is located by specifying two of the intersecting lines.
Often, maps are overlaid with a grid to help define locations. On a world map, latitude grid lines are oriented parallel to the equator, and longitude grid lines are oriented perpendicular to the equator. By specifying a latitude and a longitude, you can uniquely identify any point on the map.
In a spreadsheet, information is organized in rows and columns, forming a grid. Individual locations on the grid are called cells. Any cell in the spreadsheet is uniquely identified by its column id (usually a letter) and row id (usually a number). For example, the cell located at the intersection of column C and row 13 is identified as cell "C13."
In graphic design
Many graphic design applications provide a grid displayed over or under the contents of an image. The grid helps the artist to visually align graphic elements. Some programs provide the option to snap elements to points on the grid. When an artist using the snap feature moves an item near a point on the grid, the element "snaps" (moves automatically) to that precise location.
2. In web design, CSS Grid is a technology for defining the layout of a web page with CSS (cascading style sheets). It provides attributes and logic for organizing visual elements in two dimensions on the web page.
