@content_for_layout transition effects

I was guessing if its possible to make transitions effects for the code
that are included inside @content_for_layout(ex: new, list, edit) like a
fade out and fade in, right now im using the accordion effect of moo.fx
but the content its to much inside and sometimes takes a while to load
and show the effect properly.

Any example or advice its more than welcome, ill keep searching about
this.
