$fx() is a JavaScript animation library which is only 3.7kb.
Within a timeline, any CSS property can be altered. And also:
- you can combine effects
- group them to the chains and run parallel
- set different callbacks what gives you even more flexibility.

$fx() is definitely not an alternative to other well-known JavaScript frameworks. On the other hand it does its job (animation) good & if that’s what you need, then it saves you from loading bigger sizes of JS files.
Have a look at the examples.
