The grid and its grid lines allow you to place elements in the document by aligning them with the grid lines or nearest intersection of the grid lines. You can use the grid if you want the elements to line up at regular intervals in the document.
The grid is an invisible set of lines in the document. When you use the View > Grid Snap command, elements always align with the grid lines or nearest intersection of the grid lines. You can view the grid by clicking View > Grid Display. The grid lines do not print.
You can change the display of the grid from static to dynamic by setting options on the View tab of the Options dialog box. You can also adjust the brightness of the grid display using the View > Grid Brightness command.
When you zoom in or out, the grid lines for a dynamic grid are generated dynamically. You can set dynamic grid lines to appear at fine, medium, or coarse levels. The grid lines appear at common major measurement increments. A dynamic grid displays index lines that intersect with the darker, solid grid lines.
A static grid displays solid grid lines that do not move as you zoom in or out. You can set up the increment settings on the View tab of the Options dialog box.
