Style Best Practices
From Dreamwidth Notes
Core 2
The Dreamwidth site is going to use "core2", an updated version of the core.
This version of core will better outline the wizard placement, produce well-classed CSS output, and add some additional functionality.
It is recommended that, as much as possible, styles reference functions from core instead of rewriting them. If the return/output does not meet your needs, this may be something that can be updated from core.
Wizard
The propgroup and property names will be standardized.
CSS
Styles will use the hAtom microformat, as well as additional in-house classes. The Dream Garden layout page will be edited to reflect this.
