Safari's text-wrap: pretty improves web typography, addressing issues like short last lines, bad rag, and hyphenation. Traditional typesetting standards are used in a computer-driven layout, offering qualities such as better readability. The feature leverages paragraph-based algorithms for enhanced text presentation. text-wrap: balance is another option but should be used for shorter texts rather than long paragraphs. Performance concerns are minimal with proper implementation. The feature is actively available for testing in Safari Technology Preview 216, suggesting users explore its impact on text appearance.
