Having just been moderated on OCr unit 21 the moderator stated he was not happy that the navigation bar did not contain graphics. My question is has anyone else had this experience? Apparently a simple vector graphic when making the nav_bar is not sufficient. "the students need to use an image" was the advice "such as an of a house on the home button". When I raised the point that this was not common practice on business website design, no further advice was given. Anyone like to share how they overcome this please?
