Final answer:
Modular design in technology involves creating independent modules that are combined to form complex systems. The statement about modular design incorporating layouts within layouts is true.
Step-by-step explanation:
The statement "The foundation of modular design is layouts within layouts." is True. Modular design, especially in the context of web or software development, involves creating distinct components or modules that can be developed, tested, and maintained independently of one another. These modules are then arranged in various configurations to create complex interfaces and applications.
For example, a web page might have a modular layout where the header, sidebar, content area, and footer are different modules that fit together to form the overall page design.
