In PowerPoint a placeholder is a boilerplate container that you can use to fill in with some sort of content. When you launch PowerPoint, you will see those distinctive boxes that invite you to add some content — haven’t you noticed the “Click to add title” suggestions? All these boxes are placeholders — when selected, these boxes have a dotted border around them. Each of the default layouts comprises a collection of various placeholders — if none of the available layouts work for you, you can create your own layout with custom placeholders.
