Corrected css-doc

CSS were styled due to "coding conventions".

P.S.
Please notice that the "bad" html-doc structure were not changed - so many duplicating styling elements could be omitted (for example: .spacer).
Also there were no necessity to use nested/global classes due to html-doc structure.
