Chris,I had a feeling you were going to say that
I do have a lot of code in my style sheet, because I use the same template for several sites and change the look with different colours. My understanding is that that pushes my content further down the page as far as the SEs are concerned and that may have an effect on SERPs.
My other concern is that I put a lot of notes in my style sheet, which I don't particularly want to be seen by someone reading my source code. Not a major problem - I can delete the notes!
If FB can't read a linked style sheet, can it read a linked .js file, do you know?
Thanks!
Isobel
