我正在使用960网格系统为雇主布置网页。我正在尝试创建一个跨越6列的div，其中有三个嵌套的div，每个div跨越2列。当我尝试这样做时，最后一个嵌套的div被推出父div。我在IE 11，Chrome 37和Firefox 32上测试了这个，所有浏览器都显示父div之外的最后一个嵌套div。我正在使用alpha和omega标签，看起来omega标签不适用于最后一个嵌套div。 omega标记应该将标记div上的右边距缩小为0，并允许所有三个嵌套div适合父div。
这是HTML：
<html>
<head>
<meta charset="utf-8">
<title>gridtest</title>
<link href="12col.css" rel="stylesheet" type="text/css">
</head>
<body>
<div class="container_12">
<div class="grid_6 push_3 Box">
<div class="grid_2 alpha">
</div>
<div class="grid_2 ">
</div>
<div class="grid_2 omega">
</div>
</div>
</div>
</body>
</html>
