Applying a layout
A slide layout in PowerPoint is like a blueprint for a house; it establishes the various types of “rooms” that appear on your slide. Just as certain types of rooms contain certain types of furniture, slides can contain different types of objects. A Title And Content slide holds a title and bullet list, whereas a Picture With Caption slide holds an image and some text that describes it. The placeholders in a layout automatically format the content you add, applying settings specific to each type of placeholder.
