Where can I find a list with all Jira SD CSS elements

[Xavier]

Dear all,

I try to put some vizualisation customization on Jira Customer portal view.

By instance, adding

.cv-approval-status{display:none;}
.approver-decision{display:none;}

hide the "Approvers" list.

But I would like also to hide the "Activity" list (in center of page) and some other customization.

Is there a file / doc where I can found the decault css (Element ? Tag ? i.e .approver-decision) ?

I found a tag

.activity-item-description

but seems not working.

Thanks for all.

Regards,
