Right. I actually have no idea what is common. The whole css thing is pretty new to me. Did you 
find any examples in other applications ?

I believe though there should be a combination of two things: a widget type specifier (like 
gncdensecal) and style properties for that widget.

So a widget of type gncdensecal can have a property called "font-size" (note dashes are usually 
used in css rather than underscores).

With that you could write css like:
gncdensecal
{
    font-size: 10pt;
}

If you want to alter a property of one particular Dense Calendar, you could use the style context 
name you have set in your code, something like this
#DensCalX
{
    font-size: 10pt;
}

That's only highlevel code, not fully verified :) More details explanations and examples can be 
found here:

For default gtk widgets this is all available by default. And usually we'd want to use the second 
form (altering css properties of one particular widget instead of a complete widget class).
For our custom widgets we'd have to define these widget types and style properties ourselves.
