Jquery not working on node edit page
In the firebug(any) console, try jQuery('#edit-title').css('color', 'red'); it should work or something with the css is wrong. 

For Drupal you're really supposed to use something like this to do on document load:

(function ($) {
  Drupal.behaviors.exampleModule = {
    attach: function (context, settings) {
      $('.example', context).click(function () {
        $(this).next('ul').toggle('show');
      });
    }
  };
})(jQuery);


Check out Managing JavaScript in Drupal 7, and search for "behaviors".

@ krister.. The code is a function where the $ variable is jQuery. So in most languages you create function and declare variables that you want passed into it. Well in JavaScript you can create that in one line. 

function some_function(tmpVar){ alert(tmpVar); }
some_function("Woot!");

You can wrap the function side in ()s and it still works
( some_function )("Woot!");

Now you can put an anonymous function block instead of some_function

( function(tmpVar){ alert(tmpVar); } )("Woot!");


and finally the jQuery 

(function($){... the $ = jQuery ...})(jQuery);
