Learning jQuery 3 - Fifth Edition

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.

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, unless the queue option is set to false

Effects on multiple sets of elements are:

• Simultaneous by default
• Queued when applied within the callback of another effect or within the callback of the .queue() method
