In PowerPoint, a placeholder is a container that you can use to fill in with some content. When you launch PowerPoint, you will see distinctive boxes that invite you to add some content. Haven’t you noticed the “Click to add title,” “Click to add text,” or “Click to add picture” suggestions? All these boxes are placeholders. 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 in PowerPoint 2016 for Mac.
