OKShadow by OKFocus

OKShadow is a JQuery plugin that produces drop shadows that track the mouse cursor. Many effects are possible, including depth-of-field simulation and focus effects.

Examples

Usage

By default, OKShadow binds to a div: 

    $(function(){
    	$('#example1').okshadow();
    });

OKShadow also works on text. In this case the shadow's size and movement are restricted. 

$('#example2').okshadow({
  color: '#555',
  textShadow: true,
  xMax: 5,
  yMax: 0,
  yOffset: 3,
  fuzzMin: 1,
  fuzzMax: 3,
});

In the last example, the transparent parameter makes the text invisible but leaves the shadow, producing a ghost text effect. Additionally, CSS is used to make the text come sharply into focus on hover (use !important), while a fuzzMin setting keeps the other links blurry as the mouse grows near: 

$('#example3 a').okshadow({
  color: 'blue',
  textShadow: true,
  transparent: true,
  xMax: 0,
  yMax: 0,
  fuzzMin: 1.5,
  fuzz: 30
});

css:
  a:hover {
    color: red !important;
    text-shadow: none !important;
  }

Usage

color sets shadow color #888
textShadow applies the shadow to the text; otherwise, the shadow affects the container ("box-shadow") false
transparent sets text color to transparent for ghost text effect false
xMax horizontal movement constraint, in pixels null
xOffset horizontal offset, in pixels 0
xFactor affects blur position based on mouse distance 30
yMax vertical movement constraint, in pixels null
yOffset vertical offset, in pixels 0
yFactor affects blur position based on mouse distance 30
fuzzMin minimum blur radius in pixels null
fuzzMax maximum blur radius in pixels null
fuzzFactor affects blur radius based on mouse distance

Methods

OKShadow offers the method setoption so parameters can be changed after instantiation. It takes either a hash of parameters or a single key and value. 

$('#ok').okshadow();
$('#ok').data("okshadow").setoption({
  "color": "red",
  "fuzzMin": 10,
});
