If you follow the steps of this post : http://support.pixelcoder.net/forums/posts/5/53842ae340554

You have done most of the works to make the top logo scroll-able.

If you have already added the javascript code then just then in index.html file at line 39 replace code with this code given below :

<a href="#home">CARNA</a> </div>

That will do the work.

Thanks.
