Hi!
Is it possible to change the comment background on the ticket history?
Each comment is wrapped in a div with class="transaction Ticket-transaction message odd". This is not enough to simply adjust the CSS. So, where can I change this bit of generated HTML to add a class identifying a comment?
The part of the HTML that you are referring to is the transaction Ticket-transaction message odd class. This class is used to identify a comment in the ticket history. To change the background color of the comment, you can add a background-color property to the transaction Ticket-transaction message odd class in the CSS.
