=head1 NAME
PDF::FromHTML::Template::Element - Provide a base class for all rendering nodes
=head1 COLORS
This is the class that handles colors. Colors in PDF::FromHTML::Template are specified in
RGB format, comma-separated. Each number is from 0 to 255, with 0 being none and
255 being most. If a color is not specified, 0 is assumed. Thus, "255,0,0",
"255,0", and "255" will all result in a red color.
Colors should be used for all attributes that have the word "COLOR" in the name.
This includes (but may not be limited to):
=over 4
=item * COLOR
=item * FILLCOLOR
=back
