The HTML structure in the PDF export differs from the normal view.
There is no class or id to register specific css to the atbs as for example to hide the header and to add a page break after every tab:
Old style, before we changed the export:
We need to add some new classes and wrapping divs to allow styling again.
We need classes to style later:
The Tab Label (for example to hide it)
The Tab content
The whole Tab construct
Please add some example how you
hide the label
do a pagebreak after each tab
