The intersection of terminologies is a bit confusing, but it's really "div", "p", "span" etc. in HTML and "GtkWindow", "GtkButton" etc. in GTK+ etc. that respectively constitute a document. So the use of a leading period would be wrong. To avoid confusion those elements are called `types' in libccss. A `class' in CSS is a subset of a document's elements, not necessarily of homogeneous type. Initially, when the CSS engine primarily did drawing-routine-theming ("primitive theming") I decided to map the detail string to the CSS class selector, which made it possible to use "box.button { ... }" to theme a GtkButton. Now that I'm working towards better support for widget theming and support for sub-controls [1] like scrollbar arrows, combobox buttons ..., the class selectors may become available for a different use: Per libccss default, the style of a type "Foo" is also applied to all its derived types (contrast gtkrc, which afaik requires explicit markup "<Foo>" for that). QT is using the class selector to apply styling that would not be inherited [2], e.g. ".GtkButton { ... }" would not affect GtkToggleButton instances and other GtkButton-derived types. I am pondering this for the CSS engine as well.
