Besides, you will be able to add or change other fixed elements that will appear throughout all your presentation: your logo, the page numbers, the background color, the header, etc. In the first slide, called “Master”, you can set the paragraph style, that is, which fonts, sizes and colors you are going to use in the presentation (only two text boxes appear: a title and a body text). To do this in PowerPoint, go to View → Slide Master.
If you want to edit a master slide in Google Slides, go to Slide → Edit master. The master slides are the slides that contain the layout, the format and the structure of the elements in every slide of the presentation. In such cases, you will find the resource in the master slides. However, there might be a resource that belongs to the design itself, and thus it cannot be modified from the slide. Most of the elements are editable to allow our users to customize the template as much as possible.
