What is used to create layout or formatting changes in a portion of a document?

To create layout or formatting changes in a portion of a document, you typically use styles, formatting tools, or section breaks. Styles allow you to apply consistent formatting, such as font size and color, to specific text. Formatting tools, like those found in Word processors, enable adjustments to margins, spacing, and alignment. Section breaks can also help manage different layouts within the same document, allowing for varied formatting in distinct sections.
