Visibility of JS9 Plugin Divs

JS9 plugins can be added statically to a web page by specifying a div element with the plugin class as an attribute, e.g:

  <div class="JS9Menubar"></div>
  <div class="JS9"></div>
  <div style="margin-top: 2px;">
  <div class="JS9Colorbar"></div>
This plugin allows you to hide or show these in-page plugins. It works by setting the CSS visibility property on the divs. Note that invisible elements will still take up space on the web page.
