I use reveal.js and write my slides in Markdown code. Now I want to display my content (text, unordered list of bullet points or even an image) in a classical two-column text layout. I would prefer a solution which may be more complex in initial configuration as long as the actual writing of content in Markdown remains easy.
Since I prefer not to run a local server, I write my markdown within the main HTML file.
Update: As the first answer indicates this should be achieved with CSS. (I updated my question accordingly.) Still, I couldn't find any description how to do it with CSS.
