jQuery Sidebar Navigation with Cool Blurring Effect - Focucss

Focucss is a jQuery plugin to create an off-canvas sidebar navigation with a cool blurring effect, that will focus your users on your sidebar content, and blurring the useless content.

How to use it:

1. Create the Html for a closed sidebar navigation.

<div class="sidebar closed">
    <a href="#" id="close"><span class="entypo-cancel"></span></a> </header>
    <li><a href="#">A link</a></li>
    <li><a href="#">A link</a></li>
    <li><a href="#">A link</a></li>
    <li><a href="#">A link</a></li>
    <li><a href="#">A link</a></li>
    <li><a href="#">A link</a></li>
    <li><a href="#">A link</a></li>

2. Create a trigger to toggle the sidebar navigation. Wrap the main content in a Html element with a CSS ID 'blurrMe'.

<a href="#" id="trigger">Trigger</a>
<div id="blurrMe">

Your content goes here


3. The SVG filter for Firefox.

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <filter id="blur">
    <feGaussianBlur stdDeviation="10" />

  <filter id="blurLogo">
    <feGaussianBlur stdDeviation="1" />

4. Include the necessary jQuery library in the document.

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js'></script>

5. The jQuery script to enable the sidebar navigation.


// Toggle the blurred class
function sidebar(){
  var trigger = $('#trigger, #close'),
  menu = $('.sidebar');

   $('#blurrMe').toggleClass('blurred'); // just here

 function deploy(){



6. The required CSS/CSS3 styles.
