8.2 ⁑Themes

The appearance of the slides is governed by themes. There are five types of theme:

Presentation
A presentation theme governs the whole appearance of the presentation. A presentation theme is chosen with:

\usetheme [⟨options⟩]{⟨name⟩}
Color
A color theme governs the presentation's colour scheme. A color theme is chosen with:

\usecolortheme [⟨options⟩]{⟨name⟩}
Font
A font theme governs the presentation's fonts or font attributes. A font theme is chosen with:

\usefonttheme [⟨options⟩]{⟨name⟩}
Inner
An inner theme governs the appearance of elements that are considered “inside” a frame. (For example, the appearance of theorems or list items.) An inner theme is chosen with:

\useinnertheme [⟨options⟩]{⟨name⟩}
Outer
An outer theme governs the appearance of elements outside a frame. (For example, the headlines or footlines or whether there is a sidebar.) An outer theme is chosen with:

\useoutertheme [⟨options⟩]{⟨name⟩}

The examples above used the default presentation theme. There are a large number of themes to choose from. The rest of this section shows a selection of these themes. The selection is partly influenced by my own preferences, but partly by how well they appear in grey scale for the printed version of this book.

Example 43. Presentation Themes (Boadilla)

This document uses the Boadilla presentation theme. The resulting slides are shown in Figures 8.8 and 8.9. This theme puts the author names, affiliations, title and date in the footline. You can download or view this document.

In the above example, if

\usetheme{Boadilla}

is changed to

\usetheme{EastLansing}

then the resulting slides have a green colour scheme with a headline (shown in Figures 8.10 and 8.11).

The Montpellier theme shows the sectioning information as a tree in the headline (see Figures 8.12 and 8.13) or there's the Goettingen theme that has a sidebar with a table of contents (see Figures 8.14 and 8.15).

You can mix a presentation theme with the other types of themes. For example, if I replace the line

\usetheme{Boadilla}

from Example 43 with

\usetheme{Goettingen}
\useinnertheme[shadow]{rounded}
\usecolortheme{spruce}

then the result is as shown in Figures 8.16 and 8.17.
