A grid layout is a design framework that organizes content into rows and columns, creating a structured and visually appealing arrangement. This approach helps designers maintain alignment and consistency across various elements, making it easier for users to navigate and understand the information presented. Grid layouts are commonly used in web design, print media, and user interfaces. In a grid layout, each item can occupy one or more grid cells, allowing for flexibility in design. Popular tools for creating grid layouts include CSS Grid and Bootstrap, which provide developers with the ability to customize and adapt their designs for different screen sizes and devices.
