CSS布局 - 并排对齐两个div

问题描述

我有一个小问题。我试图使用CSS并排两个div，但是，我想中心div位于页面中央的水平，我实现了这个使用：

I have a small problem. I am trying to align two divs side by side using CSS, however, I would like the center div to be positioned horizontally central in the page, I achieved this by using:

#page-wrap { margin 0 auto; }

Thats工作正常。第二个div我想位于中央页包装的左侧，但我不能设法使用浮动，虽然我相信这是可能的。

Thats worked fine. The second div I would like positioned to the left side of the central page wrap but I can't manage to do this using floats although I'm sure it is possible.

也许最好展示我描述的例子：

Maybe its best to show the example of what I am describing:

我想把红色的div推到白色的div旁边。

I would like to push the red div up alongside the white div.

这是我当前关于这两个div的CSS，sidebar是红色div和page-wrap是白色div：

Here is my current CSS concerning these two divs, sidebar being the red div and page-wrap being the white div:

#sidebar    {
    width: 200px;
    height: 400px;
    background: red;
    float: left;
    }

#page-wrap  {
    margin: 0 auto;
    width: 600px;
    background: #ffffff;
    height: 400px;
    }

任何帮助将不胜感激。

推荐答案

如果你包装你的div，如下：

If you wrapped your divs, like this:

<div id="main">
  <div id="sidebar"></div>
  <div id="page-wrap"></div>
</div>

您可以使用以下样式：

#main {
    width: 800px;
    margin: 0 auto;
}
#sidebar    {
    width: 200px;
    height: 400px;
    background: red;
    float: left;
}

#page-wrap  {
    width: 600px;
    background: #ffffff;
    height: 400px;
    margin-left: 200px;
}

这是一个稍微不同的外观，所以我不知道你后。这将以 800px 为中心，而不是以 200px 600px code>左侧。基本的方法是你的侧边栏浮动左边，但在主div内，并且＃page-wrap 有你的边栏的宽度，因为它的左边距移动远远超过。

This is a slightly different look though, so I'm not sure it's what you're after. This would center all 800px as a unit, not the 600px centered with the 200px on the left side. The basic approach is your sidebar floats left, but inside the main div, and the #page-wrap has the width of your sidebar as it's left margin to move that far over.

根据评论更新：对于这种偏心外观，您可以执行以下操作：

Update based on comments: For this off-centered look, you can do this:

<div id="page-wrap">
  <div id="sidebar"></div>
</div>

使用此样式：

#sidebar    {
    position: absolute;
    left: -200px;
    width: 200px;
    height: 400px;
    background: red;
}

#page-wrap  {
    position: relative;
    width: 600px;
    background: #ffffff;
    height: 400px;
    margin: 0 auto;
}
