What is postmodernism?

by teb_22

I appreciate this is complex but I am struggling to understand in full a solid definition of postmodernism. My go to would be Lyotard, that it is a critique of the modern, not a historical epoch, and a rejection of meta-narratives. Yet still, I only feel about 60-70% sure what this exactly means. Any help would be greatly appreciated
