Today we will create a set of nice typography effects for big headlines using CSS3 and jQuery. There are many things we can do with CSS3 animations and transitions and we’ll explore some of the possibilites.

We’ll be using jquery.DG_lettering.js in order to style single letters of the words we’ll be having in our big headlines.

THE HTML

The structure will simply be an h2 element with an anchor inside. We’ll wrap the headline in a container:

<div id="letter-container" class="letter-container">
    <h2><a href="#">Sun</a></h2>
</div>

Then we’ll call the jquery.DG_lettering.js plugin, so that every letter gets wrapped in a span.

This example looks crazy: we’ll create a text shadow that “elevates” the letters. We’ll also create a pseudo element which has a superhero as background.

THE CSS

.letter-container h2 a:before{
    content: '';
    position: absolute;
    z-index: 0;
    width: 525px;
    height: 616px;
    background: transparent url(superhero.png) no-repeat center center;
    background-size: 40%;
    top: 0px;
    left: 50%;
    margin-left: -277px;
    transition: all 0.3s ease-in-out;
}

On hover, we will animate the background size to make the superhero larger:

.letter-container h2 a:hover:before{
    background-size: 100%;
}

The span will have the text-shadow that “elevates” the letters and on hover, we will move the letter down by adding a padding and changing the shadow:

.letter-container h2 a span{
    color: #ff3de6;
    float:left;
    position: relative;
    z-index: 100;
    transition: all 0.3s ease-in-out;
    text-shadow:  
      0px -1px 3px #cb4aba, 
      0 4px 3px #934589, 
      2px 15px 5px rgba(0, 0, 0, 0.2), 
      1px 20px 10px rgba(0, 0, 0, 0.3);
}
.letter-container h2 a span:hover{
    color: #e929d0;
    padding-top: 10px;
    text-shadow:  
      0px -1px 3px #cb4aba, 
      0 4px 3px #934589, 
      1px 1px 10px rgba(0, 0, 0, 0.2);
}

And that’s it! I hope you enjoyed creating some crazy typography effects with CSS3 and jQuery!

Hover and Click Trigger For CIRCULAR Elements With jQuery

Today we want to share one possible solution to the circle hovering problem. We’ll create a plugin that will take care of the ‘mouseenter’, ‘mouseleave’ and ‘click’ events to be triggered only on the circular shape of the element and not its bounding box.

Applying a :hover pseudo-class to an element is widely known as the classic “hovering” over an element on a web page. A problem that arose with the introduction of the border-radius property is the non-realistic triggering of the hover event when entering the bounding box of the element and not just the actual visible area. This becomes extreme when we create a circle by setting the border-radius of a square to 50% (half of its outer width and height).

Today we want to share one possible solution to the circle hovering problem. We’ll create a plugin that will take care of the ‘mouseenter’, ‘mouseleave’ and ‘click’ events to be triggered only on the circular shape of the element and not its bounding box.

CIRCULAR-Elements-With-jQuery

HOW IT WORKS

In our example, we’ll be creating a circle with some kind of hover effect. The structure will simply be:

<a href="#" id="circle" class="ec-circle">
    <h3>Hovered</h3>
</a>

And the style will be the following:

.ec-circle{
    width: 420px;
    height: 420px;
    -webkit-border-radius: 210px;
    -moz-border-radius: 210px;
    border-radius: 50%;
    text-align: center;
    overflow: hidden;
    font-family:'Kelly Slab', Georgia, serif;
    background: #dda994 url(HoverClickTriggerCircle.jpg) no-repeat center center;
    box-shadow: 
        inset 0 0 1px 230px rgba(0,0,0,0.6),
        inset 0 0 0 7px #d5ad94;
    transition: box-shadow 400ms ease-in-out;
    display: block;
    outline: none;
}

Now, we will define a class for the hover effect but not a dynamic pseudo-class :hover. The idea is to apply this class then with jQuery when we enter the circular area of our element:

.ec-circle-hover{
    box-shadow: 
        inset 0 0 0 0 rgba(0,0,0,0.6),
        inset 0 0 0 20px #c18167,
        0 0 10px rgba(0,0,0,0.3);
}

Only when we have JavaScript disabled, we’ll add the pseudo-class. This style can be found in the noscript.css:

.ec-circle:hover{
    box-shadow: 
        inset 0 0 0 0 rgba(0,0,0,0.6),
        inset 0 0 0 20px #c18167,
        0 0 10px rgba(0,0,0,0.3);
}

THE JAVASCRIPT

We are going to create a simple plugin that basically “redefines” the three events mentioned earlier. We’ll make the events only applicable on the circular shape:

$.CircleEventManager            = function( options, element ) {
    this.$el = $( element );
    this._init( options );
};

$.CircleEventManager.defaults   = {
    onMouseEnter    : function() { return false },
    onMouseLeave    : function() { return false },
    onClick         : function() { return false }
};

$.CircleEventManager.prototype  = {
    _init           : function( options ) {
        this.options = $.extend( true, {}, $.CircleEventManager.defaults, options );
        // set the default cursor on the element
        this.$el.css( 'cursor', 'default' );
        this._initEvents();

    },
    _initEvents     : function() {
       var _self   = this;
       this.$el.on({
           'mouseenter.circlemouse'    : function( event ) {
               var el  = $(event.target),
               circleWidth   = el.outerWidth( true ),
               circleHeight  = el.outerHeight( true ),
               circleLeft    = el.offset().left,
               circleTop     = el.offset().top,
               circlePos     = {
                       x     : circleLeft + circleWidth / 2,
                       y     : circleTop + circleHeight / 2,
                       radius: circleWidth / 2
                   };

                // save cursor type
                var cursor  = 'default';
                if( _self.$el.css('cursor') === 'pointer' || _self.$el.is('a') )
                    cursor = 'pointer';
                el.data( 'cursor', cursor );
                el.on( 'mousemove.circlemouse', function( event ) {
                var distance    = Math.sqrt( Math.pow( event.pageX - circlePos.x, 2 ) + Math.pow( event.pageY - circlePos.y, 2 ) );

                if( !Modernizr.borderradius ) {

                  // inside element / circle
                  el.css( 'cursor', el.data('cursor') ).data( 'inside', true );
                  _self.options.onMouseEnter( _self.$el );

                 }
                 else {

                   if( distance <= circlePos.radius && !el.data('inside') ) {                       // inside element / circle                       el.css( 'cursor', el.data('cursor') ).data( 'inside', true );                       _self.options.onMouseEnter( _self.$el );                                                   }                     else if( distance > circlePos.radius && el.data('inside') ) {

                      // inside element / outside circle
                      el.css( 'cursor', 'default' ).data( 'inside', false );
                      _self.options.onMouseLeave( _self.$el );
                    }
                   }
                }); 
            },
            'mouseleave.circlemouse'    : function( event ) {
              var el  = $(event.target);
              el.off('mousemove');
               if( el.data( 'inside' ) ) {
                  el.data( 'inside', false );
                  _self.options.onMouseLeave( _self.$el );
              }
             },
            'click.circlemouse'         : function( event ) {
              // allow the click only when inside the circle
                var el  = $(event.target);
                if( !el.data( 'inside' ) )
                    return false;
                else
                    _self.options.onClick( _self.$el );
            }
        });         
    },
    destroy             : function() {     
        this.$el.unbind('.circlemouse').removeData('inside').removeData('cursor'); 
    }
}

When we enter with the mouse in the square bounding box of our circle, we bind the ‘mousemove’ event to the element and like that we can track if the distance of the mouse to the center of the element if longer than the radius. If it is, we know that we are not yet hovering the circular area of the element.

hoverTrigger
Once the distance of the mouse is shorter than the radius, we know that we entered the circle and we trigger our custom ‘mouseenter’ event.
We also only allow the click event when the mouse is inside of the circle.
In our example we will then apply our plugin to the regarding element. In our case, we are adding the hover class on ‘mouseenter’ and removing it on ‘mouseleave’.

$('#circle').circlemouse({
    onMouseEnter    : function( el ) {

        el.addClass('ec-circle-hover');

    },
    onMouseLeave    : function( el ) {

        el.removeClass('ec-circle-hover');

    },
    onClick         : function( el ) {

        alert('clicked');

    }
})

Remember that the “normal” pseudo hover class is also defined in the noscript.css which gets applied when JavaScript is disabled.
