Hi Andorz,

Timo was talking about the inital naming of the .css file inculded in your skin. DotNetNuke is not renaming your css files, but it is searching for a  file called skin.css which should be located in the root folder of your skin.

The renaming Timo was talking about happens in the context of asp.net when you are using id in tags with the property  runat="server".  To avoid this use css classes for all html elements with the runat="server" tag.

eg. <div class="mycontentpane" id="ContentPane" runat="server"> </div>

To apply styles to your content pane use the class rather than the id .

eg. .mycontentpane { float:left;}

Cheers,

Jo
