Form is the arrangement of the general structure of an artwork while function is a relation such that one thing is dependent on another. For instance - height is a function of age or price is a function of supply and demand. A function is an abstract meaning which, by itself, has no intrinsic form. Form and function are independent dimensions along which the subject is defined.

Form ever follows function. This was the idea of architect Louis Henri Sullivan. It denotes that the two are intertwined and inseparable. This idea set forth by the architect can also be applied to any type of design
