Suppose I have a two-column layout with a bulleted list in the left column and an image in the right column (example below); I want the list points to appear incrementally and the image to appear after the list. This rmarkdown issue suggests that one can make individual bullet points incremental, but the example below doesn't have the desired behaviour.
Pandoc suggests that one use ". . ." to insert a generic 'pause' in a slide show, but I haven't been able to make this work in my example. That may be because Pandoc natively supports these formats: "S5, DZSlides, Slidy, Slideous, or reveal.js" (i.e. not including ioslides).
I am generally happy with ioslides and am not eager to invest in learning yet another slide markup system, but I guess I could switch to xaringan if the consensus is that there's no way to do what I want in ioslides ... (edit: based on this question it is possible, but not very easy, to use incremental bullets in conjunction with a two-column layout in xaringan ...)
I'd be happy with a CSS hack that would let me use some kind of <div class="pause-after"> ... </div> construction (the only CSS 'pause' stuff I've been able to find seems to be irrelevant/to be about speech/audio files).
Build an HTML from this example by cutting & pasting to a file and rmarkdown::render("test.rmd"):

title: "incremental test"
output:

## why use MMA? {.columns-2}
> - avoid omitting potentially important predictors
> - avoid overfitting
> - $\approx$ optimize bias-variance tradeoff
> - avoid stepwise approaches & pairwise comparisons
> - MMA is a **shrinkage estimator**
