# Handling of styles
#
# First there are font face declarations. These set up a font style that will be
# referenced from a text-property. The declaration describes the font making
# it possible for the application to find a similar font should the system not
# have that particular one. The StyleToCSS stores these attributes to be used
# for the CSS2 font declaration.
#
# Then there are default-styles. These set defaults for various style types:
# "text", "paragraph", "section", "ruby", "table", "table-column", "table-row",
# "table-cell", "graphic", "presentation", "drawing-page", "chart".
# Since CSS2 can't refer to another style, ODF2XHTML add these to all
# styles unless overridden.
#
# The real styles are declared in the element. They have a
# family referring to the default-styles, and may have a parent style.
#
# Styles have scope. The same name can be used for both paragraph and
# character etc. styles Since CSS2 has no scope we use a prefix. (Not elegant)
# In ODF a style can have a parent, these parents can be chained.
class StyleToCSS:
""" The purpose of the StyleToCSS class is to contain the rules to convert
ODF styles to CSS2. Since it needs the generic fonts, it would probably
make sense to also contain the Styles in a dict as well..
