Today’s DHTML trick is a smooth example of Image Cross Fading. The Javascript code for the whole page is rather short to begin with, but there was some rom for improvement. If you were to look at the original source file, just about everything except for the variable declarations and the so_xfade method can be reduced to this snippet, using jQuery:

$(document).ready(function(){
  $("head").append("<link href='xfade2.css' 
    rel='stylesheet' type='text/css'>");
  img = $("#imageContainer img").set("xOpacity",0).get();
  $("#imageContainer img:first").set("xOpacity",0.99).show();
  setTimeout(so_xfade,1000);
});

Currently, there doesn’t seem to be a more elegant way of doing it in jQuery, but I can’t really complain, considering how much more understandable the code is, compared to doing it the DOM way.
