css - 侧边菜单 div 高度不随主 div 延伸

Question

我有一个.page <div>围绕着里面的所有内容。当内容延伸时，.page <div> 也会延伸。 .

我的主要问题是 .leftBannerBackground <div>不使用 .page <div> 扩展.

我能做些什么来调整 .leftBannerBackground <div> 的高度吗？使用 .page <div> 扩展？

HTML 的简短版本:

    <div class="page">
        <div class="header">
            <div class="top_banner">
            </div>
            <div class="title">
                <h1 class="siteColor centeredText">
Header                </h1>
            </div>
        </div>
        <div class="leftBanner">
        </div>
        <div class="leftBannerBackground">

        </div>



        <div class="main">
            <!-- Content goes here -->
          <div class="leftSide">


          </div>

            <div class="rightSide" style="margin-top: 35px;"></div>


        </div>
        <div class="bottomFiller"></div>


        <div class="footer">

        </div>
    </div>

Answer 1

你有两个选择:

1. 在 .leftBannerBackground 上使用绝对定位并设置 top: 0px;和 bottom: 0px; .演示:http://jsfiddle.net/ZXLNk/
2. 使用height: 100%;在 .leftBannerBackground 上(因为你已经是)。但是为了让它工作，您还需要将所有包含元素的高度设置为 100%:.page, <body> , 和 <html> .当然，这也意味着您将无法在 .page 上使用绝对定位。演示:http://jsfiddle.net/gLzcK/
