Struggling to position the background around the embedded div#'s .. i think it's going to be something tiny i've missed for looking - any ideas?

the blue div border is just there to show me where the columns are while im changing code the div#wrapper (will be a background image when i sort it) - that green is supposed to go behind the embedded div with height adapting accordingly

code on here: http://jsfiddle.net/SparrowWoods/rREAh/689/

<div id="wrapper">
<div id="mainContent">
    <h2>A Start</h2>
                <p>

背景没有覆盖里面的 div 的原因是因为它们是浮动的。有几种解决方案。其中两个是。

  1. 为您的容器 div 设置固定高度（#wrapper）
  2. 在#maincontent 和#sideContent 下添加一个div，清除所有浮动clear:both 小提琴

在这种情况下，最简单的解决方案是在列下方使用清除浮动：

<br style="clear:both;padding:0">

您遇到的问题是您正在使用float:left将列放置在彼此旁边。正因为如此，它们被排除在流布局之外，就浏览器而言，有效地使父级为空。这就是为什么您只看到它为其填充着色。

另一种方法是使用 将列彼此相邻放置display:inline-block，但这可能会导致其他一些问题，其中出现空白。

添加一个浮点数：左；到你的包装元素：

#wrapper{
    float:left;
}
