Thanks Tom, really appreciated. Been trying some different ways and occasionally have been close to something acceptable. Will be interested to see where I went wrong.
Two examples to compare are: http://k8t.2be.myftpupload.com/asylum/asylum-news/ (without padding) and http://k8t.2be.myftpupload.com/children/children-news/ (with padding)
Just a test site to made live fairly soon – some tidying up of the rest of the css needed on my part!
Thanks for the help, theme and plugin.
