10g - CSS set to 800 px. - how to centre on screen

Question

Have set up skins, etc. in CSS and set width to 800 px. but am having trouble getting the pages to render in the centre of the screen not to the left.
I have tried setting left and right margins to auto (as this works in Dreamweaver with CSS) but this has had no effect.
Can anyone please offer a solution?
Thanks
Jo

Has anybody found a way to create a drop down menu for a horizontal top menu?
I feel half way there in that I call javascript in each top menu item
<af:commandMenuItem id="menuItem" text="#{msg[foo.label]}" action="#{foo.action}" rendered="#{foo.rendered}" onmouseover="popmenu(this)">
And include the java script for each sub menu item.
<af:outputText id="menuScript" escape="false" value="#{MenuManager.menuScript}"/>
But I can not then have clickable < af:commandLink> inside the drop down menu since then they are not parsed by ADF (included in the non-escaped output text) :-(
I can only do simple links or tried using a filter using reflection in the filter to get the backing beans and methods, but here get a null pointer exception if I try to get the: FacesContext.getCurrentInstance().getExternalContext()
Any ideas?
