Cannot hide the title slide

[gkroon]

Hi, I cannot seem to hide the title slide using the following code:

= This slide and its title are still shown
:notitle:
:revealjsdir: https://cdn.jsdelivr.net/npm/[email protected]

[%notitle]
== This slide is shown and its title is hidden, as expected

Lorem ipsum

When rendered, it still shows the title slide, even when setting :notitle: as shown above.

I'm using the following environment:

$ asciidoctor-revealjs -v
Asciidoctor reveal.js 5.1.0 using Asciidoctor 2.0.23 [https://asciidoctor.org]
Runtime Environment (ruby 3.0.6p216 (2023-03-30 revision 23a532679b) [x86_64-linux]) (lc:UTF-8 fs:UTF-8 in:UTF-8 ex:UTF-8)

I've also tried downgrading the version in my :revealjsdir: to all known versions between 4.0.0 and 5.1.0, but the title slide is shown in every version. I therefore suspect this is an issue with asciidoctor-revealjs.

Hi,
You can always add a custom css:

= This slide and its title are still shown
:customcss: css/custom.css
:revealjsdir: https://cdn.jsdelivr.net/npm/[email protected]

[%notitle]
== This slide is shown and its title is hidden, as expected

Lorem ipsum

with the following :

.reveal {
        h1 {
            display: none;
       }
}
