The only place where you can easily use custom css class names for skinning is on container divs that you define in your layout.master. For other things you should just use existing classes rendered by mojoPortal. you should not change class names on divLeft, divCenter, divRight.

You can assign different skins to different pages and this allows you to use different style rules on the same css selectors on different pages.

You can also of course add custom css classes and use them in content that is created in the editor/stored in the db.

Hi,

I know you said you read the documentation, but, I feel I must ask this question. Do you have the following in your layout.master (as described in the "Understanding the Layou.master" docs)?

<asp:Panel id="divLeft" runat="server" cssclass="leftside" visible="True" SkinID="pnlPlain">
 <asp:contentplaceholder ID="leftContent" runat="server"></asp:contentplaceholder>
</asp:Panel>
<asp:Panel id="divCenter" runat="server" visible="True" cssclass="center-rightandleftmargins" SkinID="pnlPlain">
 <asp:ContentPlaceHolder ID="mainContent" runat="server"></asp:ContentPlaceHolder>
</asp:Panel>
<asp:Panel id="divRight" runat="server" visible="True" cssclass="rightside" SkinID="pnlPlain">
  <asp:contentplaceholder ID="rightContent" runat="server"></asp:contentplaceholder>
</asp:Panel> 
   

To be clear, you need those items somewhere in your layout.master; if you leave any of them out, you will not be able to see content on your site at some point.

HTH,
