Left-aligned text is a formatting style where the text is aligned along the left margin, creating a straight edge on the left side while the right side remains uneven. This alignment is commonly used in various documents, including books, articles, and websites, as it enhances readability and provides a clean, organized appearance. In left-aligned text, each line starts at the same point on the left, making it easy for readers to follow along. This style is particularly effective for languages that read from left to right, such as English and Spanish, as it allows for a natural flow of reading.
