PowerPoint presentations comprise one or more slides. Each slide can contain text, graphics, and other elements. A number of PowerPoint features work together to help you easily format attractive slides:

• Slide layouts: Every slide has a slide layout that controls how information is arranged on the slide. A slide layout is simply a collection of one or more placeholders, which set aside an area of the slide to hold information. Depending on the layout that you choose for a slide, the placeholders can hold text, graphics, clip art, sound or video files, tables, charts, graphs, diagrams, or other types of content.
• Background: Every slide has a background, which provides a backdrop for the slide’s content. The background can be a solid color; a blend of two colors; a subtle texture, such as marble or parchment; a pattern, such as diagonal lines, bricks, or tiles; or an image file. Each slide can have a different background, but you usually want to use the same background for every slide in your presentation to provide a consistent look.
• Transitions: Transitions control the visual effect that is employed when moving from one slide to the next. The norm is to have the next slide instantly replace the previous slide with no splashy effects. But if you want, you can have one slide dissolve into the next, or new slides can push slides out of the way, or you can make it look like the wind has blown the old slide away to reveal the next slide. In all, there are nearly 50 transition effects you can choose from.
