title: R Markdown: hide spoiler text (hover over text element)
body: <p>Is it possible to hide blocks of text within .html files created with R Markdown? The elements of text should be hidden until the user hovers over the text preferentially (or clicks a button). The elements to be hidden do not concern code blocks. Currently I include text within &lt; p> &lt; /p></p>
  
  <p>It was suggested to hide text blocks by preceding each line with '>!', but R Studio does not recognize this 'markdown' approach. It just returns a text block that starts with '!'.  I prefer this simple 'hover' approach though, above Javascript and buttons.</p>
  
  <p>Any suggestions would be welcome. Thanks.</p>
