I have very simple VF Page rendered as a pdf with a section where I set inline style with margins using the following code:

<div style="margin-left:250px; margin-top:250px;">
 <apex:panelGrid columns="1" width="100%" >                       
    
        <apex:outputText value="Some Text" id="some text"/>
                
</apex:panelGrid>
</div>

The margin left property worked, however the margin-top property did not.  Could someone shed some light on this?

Thanks!
