Sorry to jump on this thread again, but I’m having similar issues with a site I’m working on. The code works fine on the home page where the content would normally be shorter than the sidebar, but on a page where the reverse is true the sidebar isn’t aligning with the content.
Working homepage: http://cccbrdev.kcacrpublicity.org.uk
Not working other page: http://cccbrdev.kcacrpublicity.org.uk/what-is-bell-ringing/
Any help or advice appreciated.
