Modern style was being applied specifically to what pertained to present times and also to what was new and not old-fashioned. Thus in the 19th and 20th centuries the word could be used to designate a movement in art. Trends in the late 1970s to early 90s include the austere, minimal look of built-ins. Modern style is essentially homogeneous appearing in most Western countries after World War I and continuing to develop through the mid-20th cent. It possesses no appellation more precise, although other labels, e.g., International style and functionalism, have also been applied. Technical progress in the development of materials was evident in the construction of modern styling.
