Question

我有一个相对简单的HTML布局，我有一个标题div，然后在下面是一个主div，左侧包含一个NavBar＆amp;右侧的ContentDiv。

我的问题是我无法使用我的NavBar＆amp; ContentDiv将显示在中心（水平），它们始终位于左侧（因此NavBars x位置为零）。

你知道为什么他们（NavBar＆amp; ContentDiv）坐在左边＆amp;没有居中？

Answer 1

试试这个：

#navBar         { display: inline; height: 700px; }
#content        { display: inline; height: 700px; }
#main           { margin: 0 auto; }

更新了代码。我不确定这是不是你要找的东西。

Answer 2

最后两个css语句说float：left。这就是为什么他们在左边=）

啊好吧....我是否正确看到了：你想要内容的左侧导航，但两者一起应该居中？

中心2浮动元素
