and then select the New file command button. Navigate to your Tutorial_Site folder,
and then to its nested style folder, supply the file Name (which does not necessarily have to
match the T itle, but should end with ".css"), and then select the Save command button.
Back in the BlueGriffon (stylesheet) Type dialogue:
select the checkbox for making the URL for the new stylesheet be expressed relative to
the location of the current webpage, and
select the OK command button.
Close the anonymous stylesheet dialogue, and in the main BlueGriffon window:
select Edit from the menu bar,
select Select All from the resulting context menu (so that the style rule will apply to
the body, and not merely e.g. a given paragraph or list item)
open the CSS Properties dialogue again and expand the Colors section,
select the Background color dot,
select black within the resulting dialogue, and
select the OK command button.
