Making it all easy with statement chaining

As I've mentioned, one of jQuery's many powerful features is statement chaining, that is, stringing multiple functions together that will be performed in the order they're added to the chain (left to right) on the selected set all in one nice string of code. For example, we can change a CSS property, hide the selected elements, and fade them smoothly with one line of code:

...
jQuery(".post").css("background", "#f60").hide().fadeIn("slow");
...

For a more in-depth example of statement chaining, let's get to our first jQuery project in WordPress.
