Hi there - grateful for any assistance please from the community. Trying to reduce the height of this survey (responsive dialogue type).

The template is being pulled from a static theme.

See attached (Image 1) - able to isolate a specific class, and set a new height for testing in the developer console. This has the desired effect.

However this CSS does not pull through, when adding via the Qualtrics portal (Image 2) - have tried different variants.

Is there any way to action this approach - or alternative methods here? 

Thanks in advance!
