Applying and modifying themes

A theme is a collection of fonts, colors, and effects that are saved as a name in the Theme Gallery. Pre-defined themes are available from the Themes group on the Design tab. Should you wish to customize your own theme, use the Fonts, Colors, and Effects icons to the right of the Themes Gallery. In my experience, it is always easier to decide on a theme prior to adding all of your content to it. Applying a completely new theme design or changing a design theme once your presentation is complete can cause a few complications, with you having to redo certain formatting elements. Follow these steps:

1. Open the presentation called Safest Solutions-Themes.pptx.
2. Click Design | Themes | More…:

3. Select a theme to apply to the presentation.
4. Notice that themes also have Variants, which are displayed just to the right of the chosen design theme on the ribbon.

5. We are also able to format the background of a slide using the Customize group (alternatively, right-click on a slide background and select Format Background... to change the background properties).
6. Once you have chosen a design theme and a variant (if applicable), the existing presentation will update all the elements on the slides with the new theme.
7. In this particular design theme example, notice that applying the new design theme has caused the first slide's main title to distort somewhat as the elements are now trying to fit into the new design theme that's been applied. Change the formatting of the title of this slide so that it looks more presentable.
8. Save the presentation to keep the design changes.
