In digital design, what does 'form' generally refer to?

In digital design, 'form' primarily refers to the shape and structure of an object. This encompasses the visual aspects of how an object is defined, including its contours, dimensions, and overall geometry. Understanding form is crucial as it significantly influences how users perceive and interact with a design. The way an object is shaped can affect its functionality and aesthetic appeal, making it an essential element for any designer to consider.

The other aspects mentioned relate to different elements of design but do not fall under the definition of form. For instance, textual content pertains to the words used, colors focus on the hue and mood conveyed, and themes refer to the overarching concepts or messages being communicated. Each of these elements contributes to a design but does so in ways that are distinct from the shape or structure that form embodies.
