Requisites

jQuery JavaScript Library

Usage

var vague = $('#yourelement').Vague({
	intensity:      3,      // Blur Intensity
	forceSVGUrl:    false,   // Force absolute path to the SVG filter,
	// default animation options
    animationOptions: {
      duration: 1000,
      easing: 'linear' // here you can use also custom jQuery easing functions
    }
});

vague.blur();

API (Public methods)

• blur : Apply the SVG filter to the element selected.
• unblur : Hide the SVG filter from the element selected.
• animate( newBlurIntensity, animationOptions ) : Animate the blur intensity to any new value.

vague.animate(
  20,
  // here you can use the normal jQuery animation options
  {
    duration:500
    easing: 'linear'
  }
).done(function(){
	console.log('Animation finished!');
});

• destroy : remove the blur effect and the SVG filter from the DOM.

Issues

• The animate method is part of the plugin but it's not recommended, it can be really slow due to the many GPU resources needed to render the blur effect on the pages
• It is not supported in the Opera browser as SVG filters over elements are not supported
• Not supported in IE10/IE11 ( because IE still sucks )
