2.3.1 Document Backgrounds

As well as containing a body, a document element can also contain the definition of the document's background via the background element and its contents. This background applies to all printed pages within this document. A document background in WordprocessingML can have a single color, as well as the application of various drawing effects such as color gradient or pattern, and a tiled or stretched image. All background information in a WordprocessingML document is stored using the Vector Markup Language (VML) syntax. The single exception to this is the background color, which is stored natively in WordprocessingML using the bgColor attribute.

Consider a simple background in WordprocessingML, which consists of a single color with a gradient fill applied:

<w:background w:bgColor="5C83B4">
  <v:background id="_x0000_s1025" o:bwmode="white" fillcolor="#5c83b4
    [3204] o:targetscreensize="800,600">
    <v:fill color2="fill darken(118) method="linear sigma" focus="100%"
      type="gradient"/>
  </v:background>
</w:bgPict>

The background consists of two components: a background fill color of RGB value 5C83B4, and the background gradient stored as a VML transformation.
