我有一个 .page<div>包含里面的所有内容。当内容伸展时， .page 也会伸展<div>。
我的主要问题是 .leftBannerBackground<div>不与 .page 扩展<div>。
我可以做些什么来使 .leftBannerBackground 的高度随 .page<div>扩展<div>？
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>
