hello group,

using pandoc to generate reveal.js slides with --self-contained data-attributes do not get converted.

Slide backgrounds can for example be set by data-background or data-background-image. (https://github.com/hakimel/reveal.js/#slide-backgrounds)
These data-attributes do not get base64-converted.

# title {data-background-image="img/bg.jpg"}

ist this intended? Base64 conversion of these data-attributed images would be good.

thanks,
christoph
