In CSS, the grid layout system is a layout method for arranging elements on a web page. It allows developers to create grid-based layouts using rows and columns, and to specify how elements should be positioned within the grid. To create a grid layout in CSS, you need to define a container element as a grid container, and its direct children as grid items. The grid container can then be used to control the layout of the grid items using a set of properties that determine how the items should be sized and positioned within the grid.
