Every art historian will tell a different story of the postmodernist era, including or excluding some of it's manifestations and estimating it's chronology. There is no one timeline, only a degree of consensus. If that was true for all other art movements before the modern era it has become almost completely subjective on contemporary art. Since Hegel's (teological) postulate of the End of History, many authors (Arthur Danto, Walter Benjamin) have expanded on the subject proclaiming the end of Art. Consequentially, if you subscribe to the idea, all that prevails is the plurality of particular and ephemeral arts with no historical relevance...
Because of this profound paradigm shift (and because it is all too recent), the linear narrative approach of History is unfit to grasp it's complexity. It is my personal opinion that a chronological approach to contemporary art (or postmodernism) is the wrong approach. Instead try to focus on each of it's singularities, without conforming them to a contrived artificial timeline.
It would take a great amount of space to properly answer this question. I must therefor direct you to the links below.
Modernism and postmodernism are philosophical views. Modernism attempts to improve daily life with technological advances whole postmodernism attempts to create progressive movements.
Postmodernism rejects the dogma and practices of any form of modernism, especially a movement in architecture and the decorative arts
Postmodernism is experimental.
The term eclectic is important to describing postmodernism because it refers to a style or approach that borrows elements from various sources, which is a defining feature of postmodernism where there is a mixing of different styles, themes, and ideas. In postmodernism, eclecticism allows for the blending of traditional and contemporary elements, challenging traditional boundaries and creating new forms of expression. This approach reflects the fragmented and diverse nature of postmodernism as a cultural movement.
Authenticity
Postmodernism does not necessarily imply meaninglessness, but rather challenges traditional concepts of truth, reason, and objectivity. It emphasizes the subjective nature of truth and the importance of multiple perspectives. While some interpretations of postmodernism may lead to a questioning of absolute meaning, others argue that meaning can be found in the diversity of perspectives and experiences.

Modernism and Postmodernism descriptions are the exact opposite of each other. Modernism is is modern thought, character and practice. An example would be pop art. Postmodernism is the movement away from modernism, making classifications sharper. An example is male vs female.
