title: Make an apex item red if it is negative
body: <p>I have some display items on the page that I want to show in Red color if their value is negative. The item's value is loaded by some PL/SQL when the page is loaded. The value is a formatted string, e.g. <code>'-$100.00'</code></p>
  
  <p>I can't set the class in the HTML Table Cell Attribute because it is unconditional.</p>
