Do margin settings affect the entire document by default?

Margin settings in a word processing application, by default, apply to the entire document. This means that when you adjust the margin settings, those changes will reflect throughout all pages of the document unless specified otherwise. The reason for this is that margins are designed to create a uniform layout and ensure that the text is consistently positioned within the printable area of each page.

Some applications do allow for different margins on specific pages or sections, but the default behavior is to apply the same margins uniformly across the document. This consistency in layout helps maintain a professional appearance in printed documents, making it easier for readers to follow the text without distraction from varying margins.
