what is a placeholder in powerpoint

In PowerPoint, a placeholder is a pre-formatted container on a slide for content such as text, graphics, or video. Placeholders are displayed in the form of a dotted rectangular box and are found in all the built-in slide layouts. They can contain text, pictures, tables, charts, SmartArt graphics, and media clips. Placeholders are specifically designed to make it easier to format slides consistently and ensure the design across an entire presentation is consistent. They can be resized, moved, and edited. Placeholders are boxes on a slide layout that you click to add content when youre creating your slides. You can add placeholders to a new slide layout or change the look of an existing slide layout in slide master view. Placeholders can only be added to slide layouts and not to specific slides of a PowerPoint presentation.
