I have just implemented a few social media avenues into my latest portfolio website, but I cannot see how I am supposed to get valid XHTML code via the W3C validator, when I have the Google+ proprietary code embedded with the core XHTML code.

My domain is : www.bfdesigns.co.uk

You will notice on the index/homepage that the Google+ button is different in shape/size to any other page on my site, and this is because I though I would try and remove the attribute size="tall" from within the proprietary code, all this does is actually remove 1 less error, so the index page has 1 error yet the contact page has 2 errors.

Any help greatly appreciated
