[Gimli]

Hier der code:

fun[B]k[/B]tion correct_layout() { if(document.getElementById('content').offsetHeight) {var div_heights = new Array(
         document.getElementById('content').offsetHeight,
         document.getElementById('navigation').offsetHeight,
         document.getElementById('features').offsetHeight
       );
       div_heights = div_heights.reverse(div_heights.sort(num_sort));
       var style_height = div_heights[0] + "px" ;
       document.getElementById('navigation').style.height = style_height;
       document.getElementById('content').style.height = style_height;
       document.getElementById('features').style.height = style_height;
}
}
function num_sort(a,b) {
 return a-b;
}
