1.1.0 • Public • Published


A jQuery plugin for legit Material-Design ripple effects.

Demo: https://matthias-vogt.github.io/legitRipple.js/

  • Lightweight: <2kb gzipped
  • Configurable: Lots of options, custom HTML, custom CSS (custom transition durations)
  • CSS based: Smooth CSS transitions
  • Legit: Nice interaction, Glorious multi-touch


legitRipple.js depends on jQuery, so make sure you have that loaded. When the DOM is ready, you can use it like this:

//ripple with default options
$(".some, .elements").ripple();
//ripple with custom options
  scaleMode: false,
  maxDiameter: "100%"

You can also use alternative syntax if you have a lot of ripple elements with different options.

  ".material": {},
  ".material.circle": {maxDiameter: "100%"},
  ".customHTML": {template: $("<p/>").text("Custom ripple content!")},
  ".callback": {
    callback: function($container, $ripple, posI, maxDiameter) {
      //is called whenever the ripple's css properties change

You can't apply the ripple effect on void elements (those that can't have child elements; <img>, <input>, …). However, you can simply wrap them and apply the effect to the wrapper element.


<link href="stylesheet" type="text/css" href="ripple.min.css">
<script src="jquery.min.js"></script>
<script src="ripple.min.js"></script>

For better loading performance, I'd recommend loading the script as non-critical content (by putting the <script> and <style> tags at the end of the body tag). Please also consider concatenating it with your other dependencies.

Install and update easily using bower:

bower install --save legitripple


Option Description Expected Input Default
maxDiameter Gives the ripple a max-width. adaptPos: true requires this to be in %; can be any unit with adaptPos: false. 100% for circles. Number with unit as String ("100%" or "3.125em") false
dragging Whether the ripple should be able to be dragged. Boolean true
adaptPos Whether to take the mouse position relative to the ripple-container's dimensions into account when positioning the ripple. Note: more info on "adaptPos" Boolean true
scaleMode How to scale the ripple while dragging:

"proportional": Proportional to the amount it was dragged. Will probably become much bigger than its container.

"fixed": Don't scale and release ripple while dragging upwards.

falsey values: Don't scale while dragging
String or falsey value "fixed"
template Set the HTML content of ripples. See: custom ripple element. NodeList, Element or true when the template is in the HTML markup null
fixedPos Gives the ripple a fixed position in the parent. true for centered position or Array with x- and y-coordinates relative to the parent's offset (e.g. [20, 40] = x: 20px, y: 40px) false
allowDragging HTML5 dragging is disabled on ripple elements by default for nicer interaction. Boolean false
unbind When set, unbinds all of the ripple's event handlers. Doesn't remove any elements or classes. (see Destroying, unbinding and overwriting) Boolean false
touchDelay Time to delay triggering of ripples on touch devices (e.g. to enable scrolling past ripple elements without triggering ripples) Time in ms as number 100
callback A function to be called each time the ripple element's style property changes function null

Option Description Expected Input Default
rippleOnHover Whether to use the ripple as a hover effect Boolean false
destination An element other than the clicked one the ripple should travel to NodeList, Element or selector String or Array of coordinates in px null

Destroying, unbinding and overwriting

Ripples can be overwritten as you'd expect:

$(".ripple.noScale").ripple({scaleMode: 0});
//.ripple has default options
//.ripple.noScale has default options and {scaleMode: 0}
$(".ripple.noScale").ripple({scaleMode: 0});
//.ripple and ripple.noScale have default options

You can also unbind event handlers from ripples or destroy all ripples.

$(".ripple").ripple({unbind: true});
//removes all event handlers from a ripple element.
//if you call it during a ripple animation, the animation
//will still complete
//stops any ripple animations in their tracks and removes any
//plugin created elements, classes and event bindings.
//calling .ripple() will still work

Custom ripples

Custom CSS

Ripples can be targeted using the .legitRipple-ripple class, their containers using .legitRipple. CSS selectors for ripples shouldn't be order-specific to target all ripples since there can be multiple ripples active in an element at once.

.container .legitRipple-ripple {
    background: yellow;
    /* You can change the transition properties too!
       Just don't try and change the width transition's easing. */
    transition-duration: .15s.9s; /*width, opacity*/

Custom elements

You can even use custom elements for ripples by setting the template option with an Element or NodeList as the value, like template: $("<p/>").text("Look, ma, I'm custom!").

Alternatively, you can set the template option to true and add the following markup to your HTML:

    Container Element
    <div class="legitRipple-template">Your custom element</div>

How the code will look when a ripple is triggered:

<div class="legitRipple">
    Container Element
    <div class="legitRipple-template">Your custom element</div>
    <span class="legitRipple-ripple legitRipple-custom">
        <div>Your custom element</div>

The custom element is used as a template and will be hidden by CSS on load. When a ripple is triggered, the custom element will be .clone()'d, the legitRipple-template class removed and wrapped in a <span/> with a legitRipple-ripple class before being appended to the ripple container.

By default, when using custom ripple elements, each direct child of .legitRipple-ripple will be scaled up to cover the entire ripple container, like:

.legitRipple-custom > * {
  position: absolute;
  top: 50%;
  left: 50%;
  min-width: 100%;
  min-height: 100%;
  transform: translate(-50%-50%);

Manually controlling ripples

Since ripple elements will only be removed on transitionend, adding css opacity: 1 !important; to their CSS will keep them alive forever. If you want to remove these ripples later, just change the CSS via jQuery like:

$(".ripple-element>.legitRipple-ripple").css("opacity", "0 !important");

Moreover, you can manually trigger ripples like in the demo by faking mousedown/touchstart events and do some crazy stuff with it.


For the callback option, you can pass a function which is called everytime the ripple's style attribute changes.

$(".elements").ripple({callback: function($container, $ripple, posI, maxDiameter) {
    /* $container: The ripple container element
       $ripple: The ripple element
       posI: An array with two indices (0 <= i <= 1) for the
            x- and y-position of the ripple relative to the parent
       maxDiameter: A string with the max-width of the ripple
            element with unit ("120%", "10em", …)

Touch support

legitRipple.js has full touch support. You can even use multi-touch for multiple ripples in different elements at the same time.


On Android, ripples don't spread in all directions equally as fast. They're positioned relative to the touch position as the touch position is positioned relative to the ripple's container.

There are a lot of similar plugins out there but this effect, hadn't been replicated in any of them AFAIK (which is not surprising since it's not documented in Google's Material Design spec either), so I decided to make my own.

Update: I did some more research and this effect can be achieved with the paper-ripple Polymer element, using the recenters attribute which makes ripples "grow toward the center of [their] container". So definitely use that if you use polymer.

Adding to the incentive was that the plugins I saw don't slow the ripple spread on mousedown and speed it up again on mouseup or don't have dragging or touch support implemented correctly.

legitRipple.js is probably also the only one which works with inline elements and has ripples with customizable HTML.

Maybe it's a bit overkill for this simple effect but that's your call to decide ;)

Browser support

This uses CSS3 transitions, so browser support is ie10+.
