Bug? title-slide-background-video but only background-opacity

[bentolor]

See :

asciidoctor-reveal.js/templates/document.html.slim

Line 86 in 35b2bfa

data-background-opacity=(attr "background-opacity")

All title slides attributes are in the form title-slide-xxx except opacity, which is only background-opacity. Is this by design or a bug?

Great catch! Introduced in aeb4fd0, PR #269. Mislabeled feature present in 3.0.0 and 3.1.0. So it has only been out there for a short while. Will fix in 4.0.0 with an upgrade note.

Yeah – I'm this strange guy actually using these weird features nobody ever think they're needed.

I'm must say I'm really quite impressed with the coverage of the rather esoteric revealjs features!

[bentolor]

Oh – it was me introducing this bug? What a shame! Sorry, @obilodeau

My latest deck for an internal presentation started using background-opacity. Haven't applied it to a title slide though. Using opacity is pretty neat, especially for video backgrounds. I was surprised by the quality of the royalty-free videos on Pixabay. I'll definitely do more of this.

I noticed that opacity hasn't been integrated into the background image new syntax though:

== !

image::landscape.jpg[background, size=contain, opacity=0.7]

I'll try to add that eventually.

I found https://www.pexels.com/ also to be an astonishing source of high-quality, no-fuss free video content.
