The problem of the non-highlighted correct answer in quizzes arises in the formal_white theme for the following reasons.
- in formal_white's config.php we can see the following settings:
$THEME->standardsheets = array('styles_layout');
///$THEME->standardsheets = true; (line commented out)
which means that formal_white does not include the standard theme's color stylesheet - but the .highlight class is not defined in formal_white's fw_color.css stylesheet
- consequently, no color will be displayed for correct answers...
I do not know if this was an oversight or done on purpose by the creator of the formal_white theme. The problem is that users who will user formal_white either as is, or as the basis of a customized theme will be puzzled at the non-display of highlight in their quizzes, and it will take them a long time to realize the cause.
May I suggest to the creator of the formal_white theme to provide a .highlight class?
