How do you convert this animate method of jQuery to CoffeeScript?

gistfile1.txt

$('#book').animate({
    opacity: 0.25,
    left: '+=50',
    height: 'toggle'
  }, 5000, function() {
    // Animation complete.
  });

I am a big fan of the clean style demonstrated by CSS Tricks. Currently my preference is to code more horizontally, so for instance I would write a 3-part .animate() chain with callbacks like this:

$('#hero-section').animate height: '0px', paddingBottom: '0px', ->
  $('#featured-content').animate opacity: '0', ->
    $('.main-content-wrapper').animate paddingTop: '25vh'

Note: It should not be overlooked that jQuery is awesome and allows one to leave out the duration parameter, which is normally the 2nd argument to .animate(), as demonstrated in other examples online. The default behavior is to accept a callback function as the final parameter, so you don't actually have to include duration if you don't want to.
