title: How to hide horizontal scrollbar in right side TOC?
body: <p>I'm using the asciidoctor-maven-plugin to generate asciidoctor.
  The output contains a right side TOC.</p>
  
  <p>When the links in this TOC get to large the TOC displays a horizontal scrollbar.</p>
  
  <p>Can I easily disable this by adding some simple css via the asciidoctor-maven-plugin?</p>
