-## Types of <code>TransitionEvent</code> ## {#transition-event-types}

-	<p>The <em>additional</em> types of transition events that can occur are:</p>
-
-	<dl dfn-type=event dfn-for=transitionevent>
-		<dt><dfn>transitionrun</dfn>
-		<dd>
-			The <a idl>transitionrun</a> event occurs when a transition is created (i.e., when it is added to the set of <a>running transitions</a>).
-			The {{AnimationEvent/elapsedTime}} in this case is equal to the value
-			defined for the <a idl>transitionstart</a> event.
-
-      Issue: Is there some more useful value we could provide here for the
-      <code>elapsedTime</code>?
-
-			<ul>
-				<li>Bubbles: Yes</li>
-				<li>Cancelable: No</li>
-				<li>Context Info: propertyName, elapsedTime, pseudoElement</li>
-			</ul>
-		<dt><dfn>transitionstart</dfn>
-		<dd>
-			The <a idl>transitionstart</a> event occurs when a transition's delay
-			phase ends.
-			The {{AnimationEvent/elapsedTime}} in this case is the result of
-			calculating
-      <code>max(min(-<a>start delay</a>, <a>active duration</a>), 0)
-      / 1000</code>
-      where the <a>start delay</a> and <a>active duration</a> values refer
-      to the values defined for the transition's <a>target effect</a>.
-
-      Note: This calculation is roughly equivalent to saying,
-      &ldquo;The <code>elapsedTime</code> is zero unless there is
-      a negative 'transition-delay', in which case the <code>elapsedTime</code>
-      is the absolute value of the 'transition-delay'.&rdquo;
-      However, it produces more useful results in some edge cases such as
-      when the there is a negative delay greater in magnitude than the
-      total duration of the animation.
-
-			<ul>
-				<li>Bubbles: Yes</li>
-				<li>Cancelable: No</li>
-				<li>Context Info: propertyName, elapsedTime, pseudoElement</li>
-			</ul>
-		<dt><dfn>transitioncancel</dfn>
-		<dd>
-			The <a idl>transitioncancel</a> event occurs when a transition is <a lt="cancel">cancelled</a>.
-			The {{AnimationEvent/elapsedTime}} in this case is zero.
-
-      Issue: Is there some more useful value we could provide here for the
-      <code>elapsedTime</code>?
-      (We could, for example, return the current time at the moment the
-      transition was cancelled so that the author can tell if the transition
-      had just started or was close to finishing and perhaps behave differently
-      in each case.
-      Doing that, however, would require implementations to store
-      additional state for each transition which would be unfortunate if
-      this is not a common use case.)

-We should define the dispatch of events more generally in light of
-possible modifications to a transition's playback using the Web Animations API
-like we do for CSS Animations (see the section on
-[[css-animations-2#event-dispatch|event dispatch]]).
-
-As part of this, we should clarify the calculation of the
-{{AnimationEvent/elapsedTime}} member for <a idl>transitionend</a> events to
-use the same <a>interval end</a> value defined for CSS Animations.
