+            <p>A <a class="def" href="#glossary-user-agent">user agent</a> must dispatch this event when a mouse wheel has been rotated around any axis, or when an equivalent input device (such as a mouse-ball, certain tablets or touchpads, etc.) has emulated such an action. Depending on the platform and input device, diagonal wheel deltas may be delivered either as a single wheel event with multiple non-zero axes or as separate wheel events for each non-zero axis.</p>
             <p>The typical default action of the <a class="eventtype" href="#event-type-wheel"><code>wheel</code></a> event type is to scroll (or in some cases, zoom) the document by the indicated amount.  If this event is canceled, the implementation must not scroll or zoom the document (or perform whatever other implementation-specific default action is associated with this event type).</p>
             <p>Due to a lack of early standardization for a mouse-wheel event type, there are several related proprietary events which have been implemented by different <a class="def" href="#glossary-user-agent">user agents</a>, with different names and characteristics.  This specification does not attempt to specify these legacy events due to lack of interoperability, but supplies the following equivalency information which may help implementers and content authors.  A <a class="def" href="#glossary-user-agent">user agent</a> may dispatch an event of one or more of the following event types as a <a class="def" href="#glossary-default-action">default action</a> of a <a class="eventtype" href="#event-type-wheel"><code>wheel</code></a> event, depending upon the property values of the <a class="eventtype" href="#event-type-wheel"><code>wheel</code></a> event and implementation support:</p>
