So I want to get rid of the gray lines that divide the rows of my collapsible content on my product page. And, I want to make the heading of each row bold. Plus, I want to make icon of each row a "+" and when you press on the row the icon changes to "-". Any ideas on how i can achieve that? I have dawn theme on my store.
The perfect style that I want to achieve for my collapsible content is provided in the attached photo, but i don't think its achievable, but if it is, please let me know 😉
