HTML and CSS Reference
Figure 13-2 Google Chrome zoomed out to show the empty div with a black border around it.
With the main content container <div id=”main” class=”group”> set to have a perspective of 1000px , its
direct child elements can be moved in that 3D space, which is what you can do with the empty <div
After you transform the empty <div class=”temp”> and move it back 500 pixels on the Z axis, it appears to
move away from the viewer, as shown in Figure 13-3.
