Create PDF from Web Page - documentation on Acrobat browser capabilities?

[DouglasDaveyWaikatoNZ]

Kia ora (Hello)

I'm spending time trying to identify what CSS styles / HTML / JavaScript support the Adobe Acrobat Pro mechanism to Create PDF from Web Page has - e.g. what can the Acrobat 'browser' do, and what can't it do.

Is there existing documentation on what Acrobat uses as a 'browser' mechanism for accessing the webpage and retrieving it to convert into a PDF?
