What are the two methods for changing margin in a document?

The two common methods for changing margins in a document are through the Page Setup dialog and the ruler. In most Word processing software, you can access the Page Setup dialog by navigating to the "Layout" or "Page Layout" tab, where you can specify exact margin measurements. Alternatively, you can use the ruler at the top of the document; by dragging the margin markers (the grey areas) to adjust the margins visually.
