opacity for background-image (from data-state) ignored when printing to PDF #1973

Open deki opened 7 years ago

deki commented 7 years ago

When I define the opacity for a background-image in CSS like this

html.background-opacity .slide-background.present {
    opacity: 0.2;
}

and use it in data-state, it works fine except for ?print-pdf.

This was also reported on Stackoverflow by another user: https://stackoverflow.com/questions/44950917/reveal-js-opacity-of-background-image-when-printing-to-pdf

Is there a way to specify the background-opacity in Markdown with Pandoc?

Sadly, this is unable to work as we don't apply states during PDF exporting as all slides will be shown. In this case, during printing, applying styles to .slide-background won't work as expected. I'm not too sure if there is any easy way to work around this.

I'm primarily concerned with HTML output, but I do occasionally use PDF output as well.
