The Ink-Drop style interaction that is added in the material design by Google using jQuery and CSS.

The new Design concept MaterialJs launched with the new Google Android 5.0 had a beautiful Ink Drop fading animation for every click. And the same was implemented in the Polymer project as well. So this is just a small breakdown for the same using jQuery and CSS. ###Demo Here ##How To : First include the inkdrop.css ,ink.js file and jQuery to your page

<link rel='stylesheet' type='text/css' href='css/inkdrops.css'></link>
<script type="text/javascript" src='js/ink.js'></script>
<script type="text/javascript" src='js/jquery.min.js'></script>

Then all you have to do is add a class 'inkMe' to the containing element that needs the ink drop effect. And Voila! when you click the element you could see the ink drop dripping

<a class='inkMe'>Regular Link</a>

##Customize You can also change the color of the ink ripple by assigning the ink-color attribute any custom class that has the backround-color set. This also works with bootstrap classes like primary, danger, etc.

<button class='inkMe' ink-color='bgBlue'>Blue Ripple on Button</button>

Where bgBlue is

.bgBlue{
    background: #39c;
}

Also you can add multiple ink-drops overlapping one another by using the multiple-ink attribute

<button class='inkMe' ink-color='bgYellow' multiple-ink=true>Button with Multiple Ripples</button>
