I have created a child theme of Twenty Eleven and want to create some pages that have a logo images instead of the entry title. I want these pages to have the sidebar template. I have tried creating new templates for these but as soon as I change the template name the layout is messed up and I can't figure out the part of the CSS that I need to update. I'm guessing there's propably a better way to do this in any case. Can anyone advise please?
