Overview of themes

A theme is a design scheme of colors, fonts, and background that you apply to your slides.

Using a theme gives your presentation a harmonious appearance with minimal effort. Text and graphics automatically take on the size, colors, and placement defined by the theme, which means less manual work as you create individual slides.

After you create a theme, it's located on the Design tab in the Themes gallery. To try out a theme, rest your mouse pointer over a thumbnail in the Themes gallery and notice how the look of your slide changes.

Here are four different themes applied to the same slide:

The preset Dividend theme
The preset Feather theme
The preset Slice theme
The preset Parcel theme
