DefinitionRepetition (反復) is the principle of reusing visual rules such as colors, typefaces, symbols and layouts throughout a document to create a sense of unity.
ExplanationIf heading colors and bullet symbols stay the same from page to page, readers can tell at once that they are looking at the same kind of information. When the rules change on every page, content of the same kind starts to look unrelated. Consistency across the whole makes a document easier to read through.
AnalogyWhen a team wears matching uniforms, you can tell who plays for it even when the players are spread across the field.
