Remarks

This element only manipulates the presentation value for the duration of the animation. When the animation completes, the effect is no longer applied.
When setting style properties on an object, the property must be initialized in the object's style. The following example demonstrates how to use the t:SET element to change the width of a div.
<HTML XMLNS:t ="urn:schemas-microsoft-com:time">
<HEAD>
<TITLE>t:SET Demo</TITLE>
<?IMPORT namespace="t" implementation="#default#time2">
</HEAD>
<BODY>
<DIV ID="oDIV" STYLE="width:100px; height:50px; border:solid black 1px;
text-align:center;">Resizing DIV!</DIV>
<t:SET attributeName="width" begin="2" to="300" dur="5" targetElement="oDIV" />
</BODY>
</HTML>
The prefix t: is used to associate this element with an Extensible Markup Language (XML) namespace. You must declare the XML namespace in the html tag of your document when using this element.
<HTML XMLNS:t ="urn:schemas-microsoft-com:time">
You must then import the tag definitions from the time2 behavior by using the IMPORT processing instruction.
<?IMPORT namespace="t" implementation="#default#time2">
The members listed in the following table might not be accessible through scripting until the window.onload event fires. Waiting for this event to fire ensures that the page is completely loaded, that all behaviors have been applied to corresponding elements on the page, and that all the behavior's properties, methods, and events are available for scripting. Using any of the behavior-defined members before the window.onload event fires could result in a scripting error, indicating that the object does not support that particular member.
This element is not rendered.
This element requires a closing tag.
