I have a site - www.sweetsilversong.co.uk that my client wants to look good on mobile devices as well as desktops.  I created the skin in Artisteer and the responsive skin was displaying properly on my mobile until I added the Logo tag in the layout.master file - <div><portal:SiteLogo id="SiteLogo" runat="server" /></div>

Since adding this tag, the responsive skin does not didplay on my mobile and it uses the desktop skin.  Can anybody tell me why this might be?
      

Joe Davis - it is a single skin, from the Artisteer artx files which has responsive CSS - If I use the site on my mobile before I add the logo tags it displays fine on my mobile using responsive menus etc, but as soon as I add the logo tag it only displays the desktop version.  I'm a novice on CSS so I am struggling to understand why it's happening.
