Output from the event callbacks

If the element that can grow is changed, it's width and height is shown here.

If the element that can move is changed, it's top and left position is shown here.

How jQuery css watch was initialized in this example using CoffeeScript (yes you should use it...):

# for the growing div:
$('#watch-me-grow').on("css-change", (event, change) =>
  $(".output_grow").text("I'm growing: width: #{change.width} height: #{change.height} ");
)
$('#watch-me-grow').csswatch({props: 'width,height',
                              props_functions: {"width":"width()", "height":"height()"}
                            })

# for the moving div:
$('#watch-me-move').on("css-change", (event, change) =>
  $(".output_position").text("I'm growing: width: #{change.width} height: #{change.height} ");
)
$('#watch-me-move').csswatch({props: 'top,left',
                              props_functions: {"top":"offset().top", "left":"offset().left"}
                            })

# for the color changing div
$('#watch-me-change-colors').on("css-change", (event, change) =>
  $(".output_colors").text("I got some new colors: #{JSON.stringify(change)}");
)
$('#watch-me-change-colors').csswatch({props: 'color,background-color'})
