Before writing your own theme try to explore existing ones with preinstalled prerequisites. Start with the simplest default theme.
Each theme can set up one or several following aspects of rendered pages:
- header
- summary
- examples
To make setup agile it's allowed to surround header, summary and examples with any
text. prefix and suffix properties are responsible for that. They can be omitted
in which can nothing is put around header/summary/examples.
To change color of header/summary/examples itself use color property.
