A grid system is a tool used in graphic design to help the designers with alignment and layout. This refers to a set of guidelines the designer may follow to ensure everything fits neatly into place. A grid is made up of intersecting vertical and horizontal lines, which serve to organize the page's elements. Websites can benefit from using a grid to arrange their design components in a manner that is both aesthetically pleasing and functional for site visitors. Different variations of grids serve different purposes while designing websites.
