Quick Styles are collections of formatting that you can apply to a document, worksheet, or presentation. For example, if you create a document by using the Modern Quick Style set, then change to the Distinctive Quick Style set, all the styles in the document (such as Heading1 and Normal) change to conform to the new styles. If you're familiar with Web design, changing a Quick Style is analogous to changing to a different style sheet when using Cascading Style Sheets (CSS). Quick Styles are available for Word 2007, Excel 2007, and PowerPoint 2007, so that you can create a consistent look for documents, regardless of the originating application.
