Defining rich formatting
Rich formatting represents structured text that incorporates visual elements beyond standard character display. The term "rich" refers to the enhanced presentation capabilities that go beyond plain text limitations.
Standard text contains only characters and basic spacing. Rich formatting adds visual hierarchy through headings, emphasis through bold and italic text, and structure through lists and tables. Colors highlight important information. Images support textual content. Links connect related resources.
The distinction matters because rich formatting requires different technical approaches for creation, storage, and display. Plain text files remain small and universally compatible. Rich formatted content needs specialized markup languages, rendering engines, and display capabilities.
Historical development
Early computer systems handled only plain text due to memory and processing constraints. Typewriters influenced initial text presentation approaches. Word processors introduced formatting capabilities in the 1970s and 1980s.
HTML revolutionized rich formatting by separating content from presentation. CSS added sophisticated styling capabilities. Modern frameworks provide component-based approaches to rich text implementation.
