Briefly describe the difference between a document theme and a style

What will be an ideal response?

As a set of coordinating fonts, colors, and special effects, a document theme enables you to create a professional, visually appealing document with a unified set of design elements. A style is a named set of formatting characteristics that you apply to text or to paragraphs. However, a style is not intended to provide an overall design for various page elements, as is a document theme.
