What is the ID or class for the Wizard Page name? In Webform 8 I am using the Attachment PDF / Entity Print to send a PDF of the submission via e-mail. 

I am able to target the field labels, fieldset and webform-elements to add CSS but cannot find the correct ID or class for the wizard page titles.

Where do I find it?
Each wizard page is rendered as details element.

Below is the Entity Print markup from the webform_example.module's 'Example: Wizard'.

&lt;details 
 class="webform-container webform-container-type-details js-form-wrapper form-wrapper" 
 data-webform-element-id="example_wizard--information" 
 id="example_wizard--information"
 open="open"&gt;    
   &lt;summary 
     role="button" 
     aria-controls="example_wizard--information" 
     aria-expanded="true" 
     aria-pressed="true"&gt;
     Your Information
     &lt;/summary&gt;
   &lt;div class="details-wrapper"&gt;
   ...
   &lt;/div&gt;
&lt;/details&gt;
