LetterFx jQuery Plugin

A jQuery plugin to apply animated visual effects to text - letters, words & custom patterns.

LetterFx works by temporarily injecting markup into the text of an $("element") and sequentially adding & removing transition-based CSS classes.

Please use responsibly.


Option Description Possible Values Default Value
fx A space seperated list of fx to apply to the letters. Options are extendable, but out of the box they include, spin, fly-left, fly-right, fly-top, fly-bottom, fall, fade, smear.
See the effects section for more info.
'spin fly-top'

Effects can happen 'in' or 'out' (eg fade-in vs. fade-out). The default direction for all effects is 'in'.

Change "backwards" to true to play the effect(s) backwards thus switching the direction to 'out.'

true|false false
timing The time (in ms) to wait between launching each letter's effect(s). Any time (in ms) greater than 0. 50
fx_duration The length of the effects for each CSS transition. Any valid value for the CSS transition-duration property (eg: "300ms" or "2s"). "1s"
word Switches default pattern from letter mode to word mode. true|false false

What to do when the letter is done with its effect.

"restore" restores letter wih its text.

"stay" leaves the letter as is.

"destroy" gets rid of the letter.

"rewind" animates back to its initial state.

"restore"|"stay"|"destroy"|"rewind" "restore"

What to do when all letters complete their effect.

"restore" restores element to its original state.

"stay" leaves the element as is.

"destroy" gets rid of the element.

"restore"|"stay"|"destroy" "restore"
sort A sorting function through which to run all matched letters. Any valid function that accepts and returns a jQuery collection. function($letters){ return $letters; }
onLetterComplete A callback function to run whenever a letter finishes its transition. Any valid function. function($letter, $element, LetterFXObj){}

Creating your own letterfx is an easy process:

  1. For your custom letterfx (we'll call it myfx), create the before class.

    Prefix your fx with letterfx- and suffix it with -before.

  2. Create the after class.

    Prefix your fx with letterfx- and suffix it with -after.

  3. Optional: add temporary styles to the element which contains the letters.

  4. Optional: add styles which apply to both -before and -after the fx.

    .letterfx-myfx-container .letterfx
  5. In your JavaScript, call your new fx.
