we will create a full page cufonized menu that has two nice features: when hovering over the menu items we will move a hover-state item that adapts to the width of the current item, and we will slide out a description bar from the left side of the page, reaching towards the current menu item.

We will use jQuery for the effect and some CSS3 properties for the style. We are not going to use any images.

So, let’s start!

 

The Markup

 

The HTML structure will consist of an unordered list that represents our menu and a div for the description elements:

<div id="slidingMenuDesc" class="slidingMenuDesc">
 <div><span>Description for "About"</span></div>
 ...
</div>
 
<ul id="slidingMenu" class="slidingMenu">
 <li><a href="#">Home</a></li>
 <li><a href="#">About</a></li>
 <li><a href="#">Portfolio</a></li>
 <li><a href="#">Work</a></li>
 <li><a href="#">Contact</a></li>
 <li><a href="#">Get a quote</a></li>
</ul>

 

We leave out the description for “Home” since there is nothing to describe. The sliding divs should just appear when we hover over the other items.

 

The CSS

 

First, we will style the menu and its navigation items and then we will style the description elements.
Let’s reset some styles:

body, ul, li, h1, h2, span{
 margin:0;
 padding:0;
}
ul{
 list-style:none;
}

 

The background is going to be dark gray:

body{
 background:#292929;
}

 

The list for the menu items is going to be positioned absolutely at the right side of the screen:

.slidingMenu {
 position: absolute;
 height:410px;
 width: 410px;
 top:40px;
 overflow:hidden;
 right:1px;
 font-family: Arial, Helvetica, sans-serif;
}

 

The menu items are hoing to float right:

.slidingMenu li {
 display:block;
 float:right;
 clear:both;
 position:relative;
 overflow:hidden;
}

 

The “mover” element will be positioned absolutely and we will give it a top and a width dynamically:

.slidingMenu li.move {
 width: 9px;
 height: 68px;
 right:0px;
 padding-right:10px;
 margin-top:2px;
 z-index: 8;
 position: absolute;
 background: #2183c4;
 background:
  -webkit-gradient(
   linear,
   left top,
   left bottom,
   from(#0771b8),
   to(#2183c4)
  );
 background:
  -moz-linear-gradient(
   top,
   #0771b8,
   #2183c4
  );
 -moz-border-radius: 8px 0px 0px 8px;
 -webkit-border-top-left-radius: 8px;
 -webkit-border-bottom-left-radius: 8px;
 border-top-left-radius: 8px;
 border-bottom-left-radius: 8px;
 -moz-box-shadow:1px 1px 5px #000;
 -webkit-box-shadow:1px 1px 5px #000;
 box-shadow:1px 1px 5px #000;
 }

 

We will give this moving hover element a very subtle background gradient and some box shadow.
The style for the link element will be as follows:

.slidingMenu li a {
 font-size:66px;
 text-transform:uppercase;
 text-decoration: none;
 color: #ddd;
 outline: none;
 text-indent:5px;
 z-index: 10;
 display: block;
 float: right;
 height: 66px;
 line-height: 66px;
 position: relative;
 overflow: hidden;
 padding-right:10px;
}

 

The descriptions will be in a relatively positioned container. We set the margin-top to the same value like the top of the menu list:

/* Descriptions */
.slidingMenuDesc{
 margin-top:40px;
 position:relative;
}

 

The div with the description span inside is going to have the same background-gradient like the mover and the same box shadow. The rounded borders are going to be on the opposite corners:

.slidingMenuDesc div{
 background: #2183c4;
 background:
  -webkit-gradient(
   linear,
   left top,
   left bottom,
   from(#0771b8),
   to(#2183c4)
  );
 background:
  -moz-linear-gradient(
   top,
   #0771b8,
   #2183c4
  );
 height: 68px;
 padding-right:5px;
 left:-5px;
 width:0px;
 margin-top:2px;
 overflow:hidden;
 position:absolute;
 -moz-box-shadow:1px 1px 5px #000;
 -webkit-box-shadow:1px 1px 5px #000;
 box-shadow:1px 1px 5px #000;
 -moz-border-radius: 0px 8px 8px 0px;
 -webkit-border-top-right-radius: 8px;
 -webkit-border-bottom-right-radius: 8px;
 border-top-right-radius: 8px;
 border-bottom-right-radius: 8px;
}

 

We need to set these element absolute, since we will adjust the top to the according current list element that we are hovering.

The description span is going to be positioned absolutely as well. This is not required but it gives you more options if you would like to apply other animation effects:

.slidingMenuDesc div span {
 font-size:36px;
 color: #f0f0f0;
 text-indent:5px;
 z-index: 10;
 display: block;
 height: 66px;
 line-height: 66px;
 position:absolute;
 right:10px;
 margin-left:5px;
 top:-3px;
}

 

And now, let’s take a look at the JavaScript!

 

The JavaScript

 

First, we will add the following scripts to our HTML head:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="cufon-yui.js" type="text/javascript"></script>
<script src="BabelSans_500.font.js" type="text/javascript"></script>
<script src="jquery.easing.1.3.js" type="text/javascript"></script>

 

And we will add the following script:

$(function() {
 Cufon.replace('a, span').CSS.ready(function() {
  var $menu   = $("#slidingMenu");
 
  /**
  * the first item in the menu,
  * which is selected by default
  */
  var $selected = $menu.find('li:first');
 
  /**
  * this is the absolute element,
  * that is going to move across the menu items
  * It has the width of the selected item
  * and the top is the distance from the item to the top
  */
  var $moving  = $('<li />',{
   className : 'move',
   top   : $selected[0].offsetTop + 'px',
   width  : $selected[0].offsetWidth + 'px'
  });
 
  /**
  * each sliding div (descriptions) will have the same top
  * as the corresponding item in the menu
  */
  $('#slidingMenuDesc > div').each(function(i){
   var $this = $(this);
   $this.css('top',$menu.find('li:nth-child('+parseInt(i+2)+')')[0].offsetTop + 'px');
  });
 
  /**
  * append the absolute div to the menu;
  * when we mouse out from the menu
  * the absolute div moves to the top (like initially);
  * when hovering the items of the menu, we move it to its position
  */
  $menu.bind('mouseleave',function(){
    moveTo($selected,400);
     })
    .append($moving)
    .find('li')
    .not('.move')
    .bind('mouseenter',function(){
    var $this = $(this);
    var offsetLeft = $this.offset().left - 20;
    //slide in the description
    $('#slidingMenuDesc > div:nth-child('+ parseInt($this.index()) +')').stop(true).animate({'width':offsetLeft+'px'},400, 'easeOutExpo');
    //move the absolute div to this item
    moveTo($this,400);
     })
     .bind('mouseleave',function(){
    var $this = $(this);
    var offsetLeft = $this.offset().left - 20;
    //slide out the description
    $('#slidingMenuDesc > div:nth-child('+ parseInt($this.index()) +')').stop(true).animate({'width':'0px'},400, 'easeOutExpo');
     });;
 
  /**
  * moves the absolute div,
  * with a certain speed,
  * to the position of $elem
  */
  function moveTo($elem,speed){
   $moving.stop(true).animate({
    top  : $elem[0].offsetTop + 'px',
    width : $elem[0].offsetWidth + 'px'
   }, speed, 'easeOutExpo');
  }
 }) ;
});

 

After we cufonize the font (all “a” elements and all “span” elements), the main function gets executed. We select the first item by default which is our “Home”. When we hover over a menu item we will move the li.move to the right position and slide out the according description item.

And that’s it! We hope you enjoyed it and find it useful!
