// 'style.css' file will contain at the end the following string "/* This line is appended to stream manually by user */"
var savingCallbacks = new UserSavingCallbacks()
                          {
                              RootFolder = "documentFolder",
                              CssFolder = "css",
                              KeepCssStreamOpened = true,
                              ImagesFolder = "images",
                              FontsFolder = "fonts"
                          };
