The BACKGROUND attribute specifies an image file to use as
the background for the page.
The BGCOLOR, TEXT, LINK,
ALINK, and VLINK attributes specify the
colors to be used for the background, text, links, active links, and visited
links respectively. (An link is active for the moment the user clicks on it,
and changes colour to confirm it has been clicked). The rrggbb is
defined by hexadecimal color codes found here.
The actual names of the colors, while not as versatile, may be used for
colorname. Valid colours are: Aqua, Black, Blue, Fuchsia, Gray,
Green, Lime, Maroon, Navy, Olive, Purple, Red, Silver, Teal, Yellow, and
White.
The LEFTMARGIN and TOPMARGIN attributes set
the margin at the left and top of the document, in pixels.
The BGPROPERTIES attribute causes the background image (set
with the BACKGROUND attribute) to remain fixed as the
document scrolls: a watermark effect.
