Add html attributes for PDF export?

[Deleted user]

Hi there,

As the question suggests, I'm looking for a way to add extra html attributes to different elements in Confluence. 

For example:
You have the standard h1 element that you can customise in the PDF stylesheet for PDF exports. I'd like to find a way to add classes to these elements. That way I could create a h1 with class "example" and another h1 that is not affected by this class.

The h1 with class "example" would then get different styling in the PDF stylesheet.

Is this possible? I am using Confluence cloud. I assume I'm going to need a plugin for this?

Thanks!
