Thanks for your help on this.
I tried the above mentioned code in the following.
wpvr block – additional css class
Shortcode block
additonal css costomising panel
child theme css style sheet
None have had any success at this point.
I tried the below code utilizing existing styling from the wordpress twenty nineteen theme to implement ipanorama and it works but not with WP VR?
[ipanorama id = "1315" slug = "vr-shae" class="wp-block-image" style="width: wide"]
