i made a toolset i call "mdslides" for making pure HTML+CSS (no JavaScript) presentations in Markdown. it's just a CSS stylesheet and an 8 line Awk preprocessor for a slide delimiter, adding just enough HTML wrapping to work with the stylesheet. the stylesheet adds page breaks at each slide so you can get a PDF by asking your browser to print/save-as-PDF. it should work with any CommonMark Markdown formatter (i use "md2html" from the MD4C project).
