ODS styles are produced
from compiled STYLE templates written in PROC TEMPLATE style syntax.
An ODS style template is a collection of style elements that provides
specific visual attributes for your SAS output.
Each style element is
a named collection of style attributes such as color, marker symbol,
line style, font face, as well as many others. For example, a density
plot uses the GraphFit style element for its visual attributes. The
GraphFit style element has attributes for color, line style, line
thickness, and so on.
Each graphical element
of a plot, such as a marker, a line, or a title, derives its visual
properties from a specific style element from the active style. The
style elements of a style are designed to ensure the goals of effective
graphics.
