How to use two-column layout with reveal.js?

Question

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 tex

Answer 1

I have found the following way to show one element in such a way it seems to be in a column layout

Text going to the right 

Text going on the left column 

But actually it doesn't work with more than one element on the right
