Repetition typically shows up on websites as repeated visual elements that appear throughout the pages on the site. Elements that can be repeated with effectiveness are colors, shapes, textures, fonts, typography, graphics, images, videos, spatial relationships, line thicknesses, headers, footers, navigation, sidebars, widgets, and on. Repeated elements in a consistent manner help to promote the organization of the website and reinforce continuity. The use of regular or irregular, even, or uneven elements can be utilized, as long as they are deployed in a uniform manner. Components can also be repeated in a gradation or progression state, where elements either get larger or small as they are repeated, as in the example of "Repetition" above. Variation in repetition helps solve the challenge of websites becoming humdrum and boring.
