Art contained in refers to the artwork that is a part of something else, for example, a book, a film, or a building. The antonym of art contained in would be standalone art, referring to artwork that exists independently without being a part of something else. Standalone art can encompass a variety of forms, from paintings and sculptures to performance art and installations. Unlike art contained in, standalone art does not rely on context or external factors to be appreciated. It exists purely as an expression of the artist's vision and can be appreciated on its own merits.
