After some cursory Googling I don't see any macros to easily create Bootstrap style reactive pages in Confluence and Jira. Our company uses Confluence as its primary internal content management system. It would be nice if page columns in Confluence and Jira would react to the size of their containers as one finds in most modern designs. Is this possible through a macro, plug-in, or built-in feature? Or, is enabling HTML and CSS the only solution?
