Move the CKEditor inline toolbar
If you want to keep this "floating toolbar" behaviour, then you can move it around using these settings.
But if you want to keep toolbar in one place, then check this plugin: http://ckeditor.com/addon/sharedspace
There's a sample, but you need to build a CKEditor package with this plugin and then you'll be able to check it.
You can simply give margin-top: -50px;
to the toolbar element if you want to place it 50px over the editor div.
