The guys from WordPress quite rightfully push hard for keeping the CLASS and ID names allocated in the default “Kubrick” Theme.
Now if you introduce new elements or you want to work with microformats, it all becomes fairly easily entangled and difficult to decipher for one who wants to add her/his own charming design features.
So we went for an approach where we kept all IDs within the markup in order not to mess with any internal references (the introduced shortcut menu makes use of those).
Classes which act as hAtom Microformats are obviously appearing according to their standard.
All other classes and new introduced IDs though carry the suffix “_liq”. That way it should make it much easier to distinguish between classes which also act as a microformat and classes which are merely there to shape things.
We added a CSS for printing in order to limit the amount of paper used for not valid information in regards to the particular medium.
We think that this approach also makes it easier to experiment when ones wants to develop a unique design, since the development (especially for beginners) should be much easier through this approach.
