I am using the consolidated CSS approach and I need to have different class names for my home skin because I want to do some custom rendering.

every time the home page renders it does not render custom classes.  the center renders like this:

<div id="ctl00_divCenter" class="art-layout-cell art-content center-rightmargin cmszone">
 

I must be missing something as I have followed the article and did all of the following below.

Any suggestions would be appreciated, thanks.

----------------------------------------------------------

I have these panels set in my layout.master

<asp:Panel id="divLeft" runat="server" visible="True" SkinID="pnlPlain"></asp:Panel>

<asp:Panel id="divCenter" runat="server" visible="True"  SkinID="pnlPlain">
<portal:Breadcrumbs id="Breadcrumbs" runat="server"></portal:Breadcrumbs>
<portal:ChildPageMenu id="ChildPageMenu" runat="server" CssClass="txtnormal"></portal:ChildPageMenu>
<asp:ContentPlaceHolder ID="mainContent" runat="server"></asp:ContentPlaceHolder>
</asp:Panel>

<asp:Panel id="divRight" runat="server" visible="True" SkinID="pnlPlain">
<asp:contentplaceholder ID="rightContent" runat="server"></asp:contentplaceholder>
</asp:Panel>

-------------------------------------------------------

I have this just above the from element:

<portal:LayoutDisplaySettings ID="LayoutDisplaySettings1" runat="server" />  
---------------------------------------------------------

I have this in my theme.skin

<portal:LayoutDisplaySettings runat="server"
LeftSideNoRightSideCss="leftside"
RightSideNoLeftSideCss="rightside-home"
CenterNoLeftSideCss="center-leftmargin"
CenterNoRightSideCss="center-rightmargin-home"
CenterNoLeftOrRightSideCss="center-nomargins"
CenterWithLeftAndRightSideCss="center-rightandleftmargins"
/>
 

thanks Joe, I updated the panels, re-published the master and theme.skin then touched the web.config cleared my browser history/cache.  The custom classes seem to not be rendering.

is there anything else that may be stopping the class rendering?  possible my layout.master is too old and missing something?

possibly:

<asp:SiteMapDataSource ID="SiteMapData" runat="server" ShowStartingNode="false" />
<asp:SiteMapDataSource ID="PageMapDataSource" runat="server" ShowStartingNode="false" />
<asp:SiteMapDataSource ID="ChildPageSiteMapData" runat="server" ShowStartingNode="false" />
<asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" runat="server" />

Joe, thank you for all your help so far- I found somethikng strange and wanted to let you know if this might be something you know of.

When I disable this setting (Allow Setting Skin for Page?) and set my home skin for the entire site the custom CSS renders fine.

If I enable that setting and set my home skin for only the home page the custom css classes does not render on the home page? 

It seems as if I can only render custom css if I have only one skin.
