Final answer:
Ragged right margins, also known as flush left margins, create a jagged appearance on the right side of the text. They allow for natural variation in line length and prevent large gaps or rivers of white space. Ragged right margins improve readability and the visual appeal of a piece of writing or printed material.
Step-by-step explanation:
Ragged right margins, also known as flush left margins, are margins in which the text aligns on the left side but not on the right side. This creates a jagged or uneven appearance on the right side of the text. Ragged right margins are often used in printing and typesetting to improve readability and create more white space.
Instead of using alignment or justification to create even lines of text, ragged right margins allow for more natural variation in line length. This can improve readability by making it easier for readers to track from one line to the next without getting lost. The uneven right margin also prevents large gaps or rivers of white space from forming in the text, which can be distracting.
Overall, ragged right margins are a design choice that can enhance readability and the visual appeal of a piece of writing or printed material. However, it's important to note that the effectiveness of ragged right margins may depend on the specific context and formatting of the text.
