Example Concept: CSS Grid allows developers to create complex layouts with fewer elements and less code by defining grid containers and placing items directly into grid cells. This reduces the need for nested Flexbox containers, which can become cumbersome and difficult to manage. With CSS Grid, you can easily specify areas, align content, and control spacing using grid-template-areas, grid-template-columns, and grid-template-rows, resulting in cleaner and more maintainable code.
