In a Nutshell

With all the variations to consider when applying effects, it can become difficult to remember whether the effects will occur simultaneously or sequentially. A brief outline might help:

1. 1. Effects on a single set of elements are:

   • simultaneous when applied as multiple properties in a single .animate() method

   • queued when applied in a chain of methods

2. 2. Effects on multiple sets of elements are:

   • simultaneous by default

   • queued when applied within the callback of an event handler
