I'm trying to change some of the colours that are displayed in the submissions.php file, without affecting the rest of my site. In particular, I would like to change the backgound colour where the learner's name is displayed and the word Feedback:. This looks like it is being defined from the cellheading definition in my theme's config.php file. See the image below. I assume that I will need to add a class definition to my styles.php file but I don't know how this should be defined. Does anyone have suggestions or alternatives?
