The document discusses different styles of text justification and formatting. Justified text can be hyphenated or not hyphenated, with hyphenated being preferable. Unjustified text can be unhyphenated, hyphenated, or ragged left. Unhyphenated unjustified text looks odd and is irritating to read, while hyphenated unjustified text reduces the ragged effect. Ragged left text has an uneven left margin and even right margin, slowing reading efficiency.
