Google Universal Analytics provides a great possibility to track custom events on your website. These feature can be used to analyze special user-interactions with e.g. advertised/highlighted content or social media links. The recorded data can be directly used to optimize your website!

The event tracking is very simple:

• Add Google Universal Analytics to your Website
• Add Event Listener to the elements you want to track
• Use the “send” command to push events to analytics: ga('send', 'event', 'button', 'click', 'nav buttons', 4);

To simplify the integration you can implment a simple data-binding which will automatically add event listeners (click) to you DOM elements. Just add an additional attribute to your elements which includes (in this example) a prefix, the event-category and the event-label (scheme: "prefix:category:label").


Example: Social Links with data-binding#

<a href="https://www.facebook.com/groups/" title="Facebook" data-event="ga:social:facebook" class="FacebookButton"></a>
<a href="https://twitter.com/" title="Twitter Stream" data-event="ga:social:twitter" class="TwitterButton"></a>

Finally, we need some javascript to process the additional attributes. You should always check if Google Analytics is enabled (maybe an adblocker is used or an opt-out option is set!) to avoid javascript errors. The following code will send an event to analytics each time a user clicks on the bound elements.

MooTools based Data-Binding#

window.addEvent('domready', function(){
  // GA loaded ? Used to avoid js errors on blocked analytics
  if (typeof ga !== 'function'){
    return;
  }
  
  // event binding
  document.getElements('[data-event]').each(function(el){
    // get event string
    var d = el.get('data-event').split(':');
    
    // format:  "type:category:name"
    if (d.length != 3){
      return;
    }
    
    // extract vars
    var evtType = d[0];
    var evtCategory = d[1];
    var evtName = d[2];
    
    // outgoing link on click event
    el.addEvent('click', function(){
      // universal analytics event ?
      if (evtType == 'ga'){
        ga('send', 'event', evtCategory, 'click', evtName);
      }
    });		
  });
});

Gigantic, image-based headers are an up-to-date web-feature. It looks amazing but they are squandering space, especially on sites with large tutorials containing long text.

This site is using a simply method which transforms the header-size depending on the current page-scroll: the users scrolls down and the header is automatically transformed to a smart toolbar – i’m calling this mode (following WordPress’ fullscreen editor) “Zen” reader mode. Need a demo ? Just open an article on this site and scroll down.

To integrate this feature into you website, you need the followindd things:

• “Standard” Header Design
• “Smart/Compact” Header Design
• Javascript Page-Scroll Observer
• Optional: Amazing css3 transition

Different Header-Styles (using LESS):#

/* Basic (default) Styling */
.navbar-beyond{
  height: 70px;
  .transition(500ms);
}

/* Smart Styling */
.navbar-beyond-light{		
  height: 45px;
  border-bottom: solid 1px #e7e7e7;	
  background-color: @color_bluegrey1 !important;
}

/* Large Navbar */
.navbar-beyond-dark{
  background-color: rgba(0,0,0,0.85);
  border-bottom: none;
}

Scroll-Observer Script (MooTools) :#

Description: user scrolls 200px down and the header is transformed by changing the css classes

var head = document.getElement('header .navbar-beyond');
... 
window.addEvent('scroll', function(){
  // get current scroll
  var s = this.getScroll().y;
        
  // dark/light topnav
  if (s > 200){
    head.addClass('navbar-beyond-light');
    head.removeClass('navbar-beyond-dark');
  }else{
    head.addClass('navbar-beyond-dark');
    head.removeClass('navbar-beyond-light');
  }
});

Header Structure (Bootstrap based example from this website)#

<!-- Fixed navbar -->
<div class="navbar navbar-default navbar-fixed-top navbar-beyond navbar-beyond-dark" role="navigation">
  <div class="container container-lg">
    <!-- Website Title + Mobile Nav Button !-->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle">
        <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="http://andidittrich.com">Beyond Technology<br /><span>beyond the visible world</span></a>
    </div>
    
    <!-- Navi !-->
    <div class="navbar-collapse hidden-xs">
      <ul id="menu-topnavi" class="nav navbar-nav navbar-right">
      ....
      </ul>
    </div>
  </div>
