markup language?

[bbolker]

I was starting to work on a new example (here) and was wondering about the markup you're using. Looking at simpleExample, you have <details> and <summary> tags (and seem to be using #### for sectioning). Are you rendering these examples somewhere? Is there guidance, other than common sense and following the existing examples, about how to apply these tags?

The format is Rmarkdown, and I am rendering with RStudio ("knit to html"). The special tags <details> and <summary> allows the user to open and closing code sections by clicking at the small triangle. I do not remember if that is standard Rmarkdown, and I recall that some browsers had problems with this when I started. Using the examples as templates should be sufficient.
