Lava Lamp Style Liquid Hover Effect - jQuery Lavalamp.js

Lavalamp.js is a jQuery plugin that offers a Lava Lamp style liquid hover effect when your mouse pointer moves between a set of elements.

It's most useful for highlighting elements as they're activated, like nav menus, list items, anchor links, etc. The effect can be easily changed to different styles using CSS.

<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/jquery.lavalamp.min.js"></script>

2. Load the latest easing library for additional easing functions. OPTIONAL.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.4.1/jquery.easing.min.js"></script>

3. Initialize the plugin on your nav list.

<ul id="demo">
  <li><a href="#1">Menu Item 1</a></li>
  <li><a href="#2">Menu Item 2</a></li>
  <li><a href="#3">Menu Item 3</a></li>
  ...
</ul>
$(function() {
  $('#demo').lavaLamp({
    // options here
  });
});

4. Customize the Lava Lamp hover effect in CSS.

ul li.backLava {
  /* back lava */
}

ul li.leftLava {
  /* left lava */
}

ul li.bottomLava {
  /* bottom lava */
}

ul li.cornerLava {
  /* corner lava */
}

  <li><a href="#3">Menu Item 3</a></li>
  ...
</ul>
