title: Create jQuery cookie, store css body color value, change page, retrieve cookie and apply body color value to new page
body: <p>I'm putting together a website where I have a Js button which fades the background body color to black / white (vice versa). I need to store the users choice of background colour and apply it throughout the entire site, from page to page. I understand cookies might be the way forward along with .css()?</p>
  
  <p>I've spend hours today trying to figure this out, and have read countless posts, some here on Stack Overflow but can't get to grips with how to retrieve a cookie value and apply it to my site's body css. Of course, I'm brand new to Js/Query and have just started learning. Very grateful if someone can point me in the right direction, a good tutorial with examples would be a lot of help.</p>
  
  <p>Many thanks.</p>
