Blinds Transition (filter)

Last updated: October 29th, 2008

The Binds Transition reveals content by opening and closing "blinds" Defined via IE's CSS filter property and applied through JavaScript, here is its basic syntax:


filter :progid:DXImageTransform.Microsoft.Blinds(attribute1=value1, attribute2=value2, etc);

Syntax (post IE8):

-ms-filter: "progid:DXImageTransform.Microsoft.Blinds(attribute1=value1, attribute2=value2, etc)";

Note: See "Difference in syntax between pre IE8 and IE8+ browsers" for more info on the changes to the filter syntax in IE8+.


<style type="text/css">

width: 90%;
-ms-filter: "progid:DXImageTransform.Microsoft.Blinds(duration=5)";
filter :progid:DXImageTransform.Microsoft.Blinds(duration=5);


<div id="somediv">Some DIV</div>

Syntax Via Scripting

//To define a new Blinds filter on an element ="progid:DXImageTransform.Microsoft.Blinds(attribute=value1, attribute2=value2)"

To access an existing property within the Blinds filter:

//To access an existing property within the Blinds filter via the filters[] object
object.filters[x].Property1=value1 //where "x" is the position of the filter within list of filters on element

<div id="mycontent" />
<img src="test.gif" /><br />

divbox.filters[0].apply() //capture initial state of DIV (screenshot)
divbox.innerHTML="Hay, content has been changed!" //change DIV's content (though changes not visible yet due to above capture
