Access facilitates form and report design by enabling you to "snap" your form and report controls to a grid. When the grid is turned on, Access limits where you can move your controls. Drawing lines through the allowable spots forms a grid of horizontal and vertical lines on your form or report’s body. If you’d like to make those gridlines visible on your form or report, you can turn them on quickly. The gridlines are black by default, but you can change their color, line style, and thickness by using the controls in the Gridlines group on the Design tab. Feel free to play around with different gridline appearances until you find the setting combination that looks the best on your form or report.
