Thank you so much, that did indeed work 🙂
The only other thing is that the left hand column (with the symbol image) stayed all the way to the left. Do you know how I can move this to the middle of the screen too? So that it still lies against the blog.
You see I learnt from another post how to have a background image on the left hand side only, which I have done and it looks great. What I would like to do is move the left hand column over to the middle or even extend it so that the whole of the left hand side has the patterned background.
I hope this makes sense.
