A frame is a container used to group related graphical elements, often serving both functional and aesthetic purposes. In art and design, it acts as a boundary that enhances or contrasts with the visual content it encloses. Authors like Birge Harrison emphasized its role in harmonizing with or contrasting against a painting’s composition, while Henry Rankin Poore highlighted its necessity for achieving balance and unity.
Samuel Smiles even likened natural elements like plants to frames, framing scenes without artificial borders. These perspectives reveal the frame as a versatile tool—both structural and symbolic—shaping perception and emphasizing the relationship between content and context.
