Flippable

</h1>
|

<p>
|

The flip effect simulates a flip between a front and back view of an object
|
|
|
|
|
by means of a 3D rotation. The DOMFlippable class implements this effect for two
|
|
|
|
|
DOM nodes, one as the front view, the other as the back view. Both views are connected
|
|
|
|
|
via a HTML template that defines the placeholders for front and back views. The
|
|
|
|
|
style file "css/flipeffect.css" holds reasonable default styles for this kind of
|
|
|
|
|
templates.

|
<p>
|
|
|
|
|
The SVG buttons have to be wrapped in an HTML DOM element which handles events. Otherwise,
|
|
|
|
|
the viewbox of the SVG will interfere with the coordinate transformation.
