Answer:
Modern art includes artistic work produced during the period extending roughly from the 1860s to the 1970s, and denotes the styles and philosophies of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation. Postmodern art is a body of art movements that sought to contradict some aspects of modernism or some aspects that emerged or developed in its aftermath. In general, movements such as intermedia, installation art, conceptual art and multimedia, particularly involving video are described as postmodern. Contemporary art is the art of today, produced in the second half of the 20th century or in the 21st century. Their art is a dynamic combination of materials, methods, concepts, and subjects that continue the challenging of boundaries that was already well underway in the 20th century.
