The margin-left on p elements in the Fluido skin leads to a rugged indentation, and there is no way to avoid it in a typical Mojo site doc page.
Consider for example the test-mojo page: On this page, each of the parameter descriptions is not enclosed in p elements. In the overview table this leads to a proper alignment with the "User property" and "Default value" lines because they are also not enclosed in paragraphs.
In the "Parameter Details" section however, the parameter names are enclosed in p elements, making the parameter descriptions look as if they have a negative indentation.
Enclosing the parameter descriptions in p elements (in the Mojo sources) would help for the parameter details section, but this then leads to a rugged indentation in the overview table.
So, since it cannot be ensured that p elements are used everywhere, Fluido should not assing a left margin to them.
