A theme is a set of styles that you can copy into a document, immediately giving it a different appearance. They are normally used for Web and Intranet pages although can be used for printed pages. Themes do not include autotext entries, macros, etc. Just the following visual elements:
Background colours and/or graphics
Heading styles and Body text
Table borders and hyperlink formatting
Custom bullets and horizontal lines
To apply a theme choose (Format > Theme). You can easily view your document in a different theme by using (Format > Theme, Style gallery.
The style gallery does not attach a different template to your document. It copies styles from that template into your document. Any existing formatting settings will be overwritten.

Themes are especially suited when you are creating web pages.
These contain formatting that visually communicates a wide variety of moods and messages from the informal to the corporate.

When you choose a theme Word changes the styles in your document to reflect the formatting in the theme.

Themed documents are by definition HTML documents.
If you select a theme for a Word document Word will automatically convert it to HTML.
