Silva API
When developing templates and extensions you’ll need to consult the Silva API. This is maintained on the docs site, where you’ll find a listing of all interfaces.
Theming Silva
A new theming system, “silva.core.layout”, which is based on Zope3 and Grok has been designed. It works a bit like the now deprecated “SilvaLayout”, but is much easier to use. The goal is to make it possible for non–Zope developers to make Silva layouts.
Now, the default layout provided by Silva is implemented using this new technology. It can be used as an example for making your own layout.
