Get Shift Done: Tips and Tricks
When you associate a slide master with a Microsoft PowerPoint 365 presentation, it stores information about that presentation’s visual theme and layout, including background images, fonts, effects, and placeholders. PowerPoint includes quite a few slide masters by default, but creating your own allows you to make global customizations to your entire presentation in a single stroke, saving an enormous amount of time and frustration.
Every presentation contains at least one slide master by default. To edit it, we must enter the Slide Master View. To do so, navigate to the View ribbon and select Slide Master
within the Master Views
group.
