The HTML+TIME capability in IE 5.5 and up allows you to end a parent's time line when the first child becomes inactive. You specify it by:

object.endSync = childID;

In the following HTML+TIME object, the parent element becomes inactive when hdg3 becomes inactive:

Heading 1

Heading 2

Heading 3

Heading 4

Heading 5
Heading 6


Notice that if you click the button after the specified child becomes inactive, the parent element will end immediately. Here is the definition of the HTML+TIME object above:

<HTML>
<HEAD>
<TITLE>Style Action</TITLE>
<STYLE>
    .time {behavior:url(#default#time2);}
</STYLE>
<XML:NAMESPACE PREFIX="t"/>
</HEAD>
<BODY>
<t:PAR CLASS="time" REPEATCOUNT="1" ID="parallel">
    <H1 ID="hdg1" CLASS="time" STYLE="color:red;" 
	TIMEACTION="style" BEGIN="0" DUR="5">Heading 1</H1>
    <H2 ID="hdg2" CLASS="time" STYLE="color:red;" 
	TIMEACTION="style" BEGIN="0" DUR="10">Heading 2</H2>
    <H3 ID="hdg3" CLASS="time" STYLE="color:blue;" 
	TIMEACTION="style" BEGIN="0" DUR="15">Heading 3</H3>
    <H4 ID="hdg4" CLASS="time" STYLE="color:blue;" 
	TIMEACTION="style" BEGIN="0" DUR="20">Heading 4</H4>
    <H5 ID="hdg5" CLASS="time" STYLE="color:green;" 
	TIMEACTION="style" BEGIN="0" DUR="25">Heading 5</H5>
    <H6 ID="hdg6" CLASS="time" STYLE="color:green;" 
	TIMEACTION="style" BEGIN="0" DUR="8">Heading 6</H6>
</t:PAR>
</BODY>
</HTML>

And here is the definition of the button:

<FORM>
<INPUT TYPE="button" VALUE="End when hdg3 is Done" onclick="parallel.endSync='hdg3'">
</FORM>
