Khadda has been considered to be among the founders of contemporary Algerian painting and one of the many representatives of the "sign painters." He debuted in 1960. His influences included Cubism and Arabic calligraphy. He tended toward the non-figurative or abstract. He represented a generation of Algerian artists who combined the ideas of calligraphic heritage and formal language of Western formal writing through Western abstraction through the 1950s.
