Q: Positioning video in fixed layout epub

Hi.

How can i positioning video in fixed layout page?

here is the xhtml contents.

<video src="videos/video1.mp4" poster="images/video1.png" width="300" height="200" preload="auto" controls="true"></video>

I want to change position of video but don`t know how.

I used "top", "left" property but it not work.

<video src="videos/video1.mp4" poster="images/video1.png" top="100" left="200" width="300" height="200" preload="auto" controls="true"></video>

I saw book in iBookstore "The Beatles Yellow Submarine" and see video can move any position.

Please help.
