Thank you @PhilP @snds-zuora-117
I agree, that exposing the CSS will allow for more control and greater customization. This is something we're reviewing as well as possibly exposing the design tokens that zeroheight uses so that you can customize pretty much everything (space between paragraphs, layout dimensions, navigation size etc.) and create a truly branded experience.
I've also added both your +1's, thank you for the feedback, it's always very useful for us 😀
