Display the Grid
Before we start creating the master slides, it is useful to have the grid displayed. The grid acts as a visual aid when positioning text or graphics on slides. In Normal View, make the grid visible by clicking on the menu bar, View|Grid and Guides and set the grid size to 0.083 inches (the default setting). You also need to select Display grid on screen, as shown below.
The Snap objects to grid feature is useful as it allows you to easy position (align) elements on the grid in the Slide View area. Sometimes you have to switch this feature off, especially if you want to absolutely position an element on a slide. For now, however, keep this feature on (as shown below).
Then, click OK.
