 * what code do I add to my child theme so my theme modifications will not be lost.
   I think it’s something to do with functions.php. Want to update to 3.3.

 * Your child theme modifications shouldn’t be touched with an upgrade to 3.3
    Is
   you theme a child of 2010 or 2011? If so you can choose to update those themes
   separate from the 3.3 core upgrade.

 * I modified my background color, header image, etc with twenty eleven. THEN after
   that I made a twentyeleven-child and added style.css
 * I am under the impression that if I upgrade to 3.3 that my changes I made on 
   themes (background color , header image, etc) will go back to the default settings.
   Are you saying that they won’t?
 * Thanks.. i’m new to all this

 * I haven’t lost backgrounds or headers when updating mine. But I made a proper
   child theme in the beginning. Make sure you have the header img located in themes/
   child-theme/images
    and that the child CSS is updated to whatever color you are
   using for the background.
 * If you just copied the whole theme into your child theme I don’t know what will
   happen.

 * I already updated to 3.3 and I didn’t lose background or header changes. I don’t
   have the header image located in the child theme and I’ve never copied the entire
   theme- only started my own style.css in child. I am very new to css code. Can
   you tell me the exact code from twenty eleven I would put in my twenty eleven
   child? Even though I’d already updated without changes – I’d still like to add
   code to child to be safe.
