You are relying on "position: relative", that's not a very wise choice... You should use "line-height: 0" with "vertical-align: sub" and "vertical-align: super" instead, or simply with <sub> and <sup>.

Thanks, no one else's suggestions used 'relative' either

I'll have to be more careful in copying code fragments from the web.
