Remarks

When revealed by a transition, any text that covers a Gradient procedural surface is initially exposed as transparent. After the transition has finished, the text is updated to the applicable color.

The object that the filter is applied to must have layout before the filter effect will display. you can give the object layout by setting the height or width property, setting the position property to absolute, setting the writingmode property to tb-rl, or setting the contenteditable property to true.

you can assign multiple filters or transitions to an object by declaring each in the filter property of the object. the following div declaration assigns two filters and a Wheel transition to a div element.

<DIV STYLE="width:100%; filter:
progid:DXImageTransform.Microsoft.MotionBlur(strength=13, direction=310)
progid:DXImageTransform.Microsoft.Blur(pixelradius=2)
progid:DXImageTransform.Microsoft.Wheel(duration=3);">
Blurry text with smudge of gray.</div>     

When multiple filters are applied to an object, each filter is processed in source order, with the exception of procedural surfaces, which are computed first. To emphasize a filter's effect, place it last in source order or on the object's parent. Always place transitions last in source order.
