title: How to get Chrome's vintage audit panel in 2017? (How to use Chrome's Audit tool to remove unused CSS?)
body: <p>I'm trying to follow this tutorial that was written back in 2014: <a href="https://www.labnol.org/internet/remove-unused-css/28635/" rel="noreferrer">https://www.labnol.org/internet/remove-unused-css/28635/</a>.</p>
  
  <p>It says there should be a <code>Remove unused CSS rules</code> section that appears after running an "audit" in the devtools.</p>
  
  <p>I'm currently using Chrome 60.0.3112.90 on Windows and there is no such section. It's not even in the <a href="https://developers.google.com/web/tools/lighthouse/audits/blocking-resources" rel="noreferrer">specs</a>.  Was it replaced by <code>Reduce render-blocking stylesheets</code>? If yes, how is it the same?</p>
