<div class="content">
<div class="primary">.primary</div>
<div class="secondary">.secondary</div>

方案二、利用margin边距+浮动实现两列布局方案 （浮动脱离文档流，不占据位置）

</style>

<body>
<div class="content">
<div class="primary">.primary</div>
<div class="secondary">.secondary</div>
</div>
</body>
</html>
方案三、利用margin边距+绝对定位实现两列布局方案 (方案三的实现本质与方案二一致)
