The current state of the Presentation Mode is, unfortunately, quite underwhelming.
However, a large part of it can be fixed by simply adding some custom CSS.
.reveal {
& .embedded {
aspect-ratio: 16/9;
height: auto!important;
}
& ol ol {
list-style-type: upper-roman;
& ol {
list-style-type: lower-latin;
}
}
}
The above will:
- Fix the rendering of the preview window
- Style the first three levels of nested ordered lists differently.
