| Size control |
Fully customizable using grid-template-rows and grid-template-columns. |
Controlled by grid-auto-rows and grid-auto-columns, or defaults to auto. |
| Default Behavior |
Does not change unless explicitly defined. |
Automatically adapts to items placed outside the explicit grid. |
| Complexity |
Requires more planning for layout structure. |
Easier to implement for unstructured or variable content. |
| Flexibility |
Rigid structure with defined rows and columns. |
Flexible and adapts to dynamically placed content. |
| Performance |
Potentially more performant as the layout is predefined. |
May require additional browser computations for implicit grid generation. |
| Use case |
Useful when the grid structure is predictable and defined upfront. |
Useful for dynamic layouts where content is unknown or changes frequently. |
