title: show hide html code/content using nav menu
body: <p>I have a single pay-per-click (PPC) landing page that has a menu at the top of Home / Services / About</p>
  
  <p>I do not want to have two other pages for Services/About. I just want to change the content &amp; replace everything including and after <code>div class="inner"</code> through <code>!--inner--</code> based on a services click or about click.</p>
  
  <p>So when landing on the page the home content defaults but when the services nav is clicked, it just changes everything including and after <code>&lt;div class="inner"&gt;</code> through <code>&lt;!--inner--&gt;</code> html content and all.</p>
