align=center doesn't work on divs.
try this:

thanks but i have tried that and this way but it still doesnt work for some reason
[HTML]#Layer1 {
position:absolute;
width:800px;
height:800px;
margin-right:auto;
margin-right:auto;
}[/HTML]
is it the position absolute that i need to delete? might try that now

nope not the position absolute either:rolleyes:

indeed, it won't work with absolute positioning

use
don't use
and don't forget

aha thanks your a star! do you know how i keep the divs inside this div from moving?
i.e there left and top attributes?

ive got the main layer to staycentral thanks. but how do i keep the layers on top of this in the same position on that layer when the browser size changes?

this is how i have set the layers over another layer
[HTML]<div class="style1" id="Layer1"><img src="dmlayer1.png" width="800" height="800" />
<div id="Layer7"></div>
<div id="Layer6"></div>
<div id="Layer5">
<div align="left"> </div>
</div>
<div id="Layer4">
<object classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="501" height="115">
<param name="movie" value="dmtitle.swf" />
<param name="quality" value="high" /><param name="LOOP" value="false" />
<embed src="dmtitle.swf" width="501" height="115" loop="false" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash"></embed>
</object>
</div>
<div id="Layer2">
<object classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="150" height="150">
<param name="movie" value="fruitdm.swf" />
<param name="quality" value="high" />
<embed src="fruitdm.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="150" height="150"></embed>
</object>
</div>
</div>[/HTML]

and this is how one of the layers is currently set out in css

[HTML]#Layer3 {
position:absolute;
width:200px;
height:115px;
z-index:2;
left: 314px;
top: 32px;
background-color: #FFFFFF;
}[/HTML]

In all of this discussion, "doctype" hasn't been mentioned. It is impossible to tell you what HTML/CSS code to use if we don't know which version of HTML/CSS you're using.
