A theme is a predefined combination of colors, fonts, and effects that can be applied to your presentation. PowerPoint includes built-in themes that allow you to easily create professional-looking presentations without spending a lot of time formatting. You can modify themes by combining the colors, fonts, and effects from different themes, and you can customize them even further by creating your own sets of colors and fonts.
In this lesson, you will learn how to modify theme colors, theme fonts, and theme effects, and apply a background style.
