yep it's pretty easy with FF and opera. I'm sure it's just a simple line or two to get IE working too.
http://h1.ripway.com/stirfry/index.html
there's a simple script on this page. View the page source Save it and use it. The variable used is global and I switch it back to 0 between transitions. it should simple to follow since I managed to create it. LOL

I actually borrowed from the "fake CSS lightbox script" Google turns up.

// Basic Element Animator (21-February-2009)
// by Vic Phillips http://www.vicsjavascripts.org.uk

// To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
// With the ability to scale the effect time on secified minimum/maximum values<br />
// and with three types of progression 'sin' and 'cos' and liner.

// **** Application Notes

// **** The HTML Code
//
// when moving an element the inline or class rule style position of the element should be assigned as
// 'position:relative;' or 'position:absolute;'.
//
// The element would normally be assigned a unique ID name.
//

// **** Executing the Effect(Script)
//
// The effect is executed by an event call to function 'zxcBAnimator('width#',document.getElementById('tst'),10,800,5000,[10,800],'sin');'
// where:
// parameter 0 = the mode(see Note 2).                                                                     (string)
// parameter 1 = the unique ID name or element object.                                                     (string or element object)
// parameter 2 = the start position of the effect.                                                         (digits, for opacity minimum 0, maximum 100)
// parameter 3 = the finish position of the effect.                                                        (digits, for opacity minimum 0, maximum 100)
// parameter 4 = (optional) period of time between the start and finish of the effect in milliseconds.     (digits or defaults to 2000 milliSeconds)
// parameter 5 = (optional) to scale the effect time on a secified minimum/maximum.                        (array, see Note 5)
//                 field 0 the minimum. (digits)
//                 field 1 the maximum. (digits)
// parameter 6 = (optional) the type of progression, 'sin', 'cos' or 'liner'.                              (string, default = 'liner')
//                'sin' progression starts fast and ends slow.
//                'cos' progression starts slow and ends fast.
//
//  Note 1:  The default units(excepting opacity) are 'px'.
//  Note 2:  Examples modes: 'left', 'top', 'width', 'height', 'opacity.
//           For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
//  Note 3:  To 'toggle' the effect include '#' in parameter 0.
//           The first call will set the toggle parameters.
//           Subsequent calls with '#' in parameter 0 and the same start and finish parameters will 'toggle' the effect.
//  Note 4:  The function may be re-executed with a different set of parameters (start/finish time or period)
//           whenever required, say from an onclick/mouseover/out event.
//           The period parameter will be retained unless re-specified.
//  Note 5: parameter 5 is of particular use when re-calling the effect
//          in mid travel to retain an constant rate of progression.
//
// **** Advanced Applications
//
//  It may be required to access the current value of the effect.
//  The element effect is accessible from the element property
//  element effect = elementobject[mode.replace(/\W/g,'')+'oop'];
//  where mode is parameter 0 of the initial call.
//  An array storing the current, start and finish values of the element effect may be accessed
//  from the element effect.data as fields 0, 1 and 2 respectively
//

// **** General
//
// All variable, function etc. names are prefixed with 'zxc' to minimise conflicts with other JavaScripts.
// These characters may be changed to characters of choice using global find and replace.
//
// The Functional Code(about 2.06K) is best as an External JavaScript.
//
// Tested with IE7 and Mozilla FireFox on a PC.
//



// **** Functional Code - NO NEED to Change
