<h1>Creating and Positioning an Overlay</h1>
<div class="exampleIntro">
  <p>Overlays are extensions of Modules and differ in the sense that the float <em>above</em> the normal page flow.  They can be positioned in three different ways: By fixing them to the center of the viewport (overlay1 below), by specifying a position (overlay2), and by positioning them relative to a context element (overlay3).</p>
<p>Use the buttons in the example below to show and hide the three Overlay instances.</p>

<h1>Using the Overlay Manager to Manage Multiple Panels</h1>
<div class="exampleIntro">
  <p>OverlayManager allows you to manage multiple Overlays (and Overlay subclasses like Panel, Dialog, SimpleDialog and Tooltip) on the same page, giving focus and z-index supremacy to the focused overlay and providing you with event hooks to respond to focus and blur of your overlays with your own scripts.</p>
<p>Use the buttons below to show and hide the overlays in this example"s OverlayManager group.  Click within differnt overlays and drag them around to get a sense for how OverlayManager provides a light, operating-system-like feel to the interaction.</p>
