Given below are the steps to customize your slide master. Using features like copy/ paste and format painting you can make changes to different sections within the presentation to make them look similar, however, if you want to use a theme and background throughout the slide, using the slide master is a simpler and more graceful way of approaching it.
Every presentation has at least one slide master, but you can have more than one. Slide master is simple way of applying changes to the entire slide.
