Modernizr CSS3 Generated Content test

css3gencon.js

// Using the new exposed styleElem method we can hook into the internal DOM injection code that modernizr uses. 
// This make doings tests like this easy!

// Opera is currently the only browser to support CSS3 generated content, which will replace all the elements content 
// with the content properties value.

Modernizr.addTest('css3generatedcontent', function () {
    var bool;
    
    Modernizr.testStyles("#modernizr { content:':)' }",function(node){
        bool = node.offsetHeight >=1;
    });
    
    return bool;
});
