Part III Changing the Way Things Look
beamer offers ways to change the appearance of a presentation at all levels of detail. On the top level, themes can be used to globally change the appearance conveniently. On the bottom level, templates allow you to specify the appearance of every minute detail individually.
Two important aspects of the “appearance” of a presentation are treated in extra sections: colors and fonts. Here, too, color and font themes can be used to globally change the colors or fonts used in a presentation, while you can still change the color or font of, say, block titles independently of everything else.
