bootstrap hero-单位高度-单张

Question

我有一个基本的bootstrap布局，有一个导航栏和一个侧边栏(Span 3) + map(span 9)。我的问题是，当我在浏览器中查看此代码时，地图看起来如下所示：http://dl.dropbox.com/u/15923835/bootstr.jpg

但我想要一个固定的地图大小(它应该覆盖80%的页面的东西。我试着在每个DIV中设置一个固定的高度，但什么也没有发生。你有什么意见建议？

为我糟糕的技术解释道歉(我正在努力学习)

以下是代码的副本：

<div class="container-fluid">
  <div class="row-fluid">
    <div class="span3">
      <div class="well sidebar-nav">
        <ul class="nav nav-list">
          <li class="nav-header">Sidebar</li>
          <li class="active"><a href="#">Link</a></li>
          <li><a href="#">Link</a></li>
          <li><a href="#">Link</a></li>
          <li><a href="#">Link</a></li>
          <li class="nav-header">Sidebar</li>

如快速入门中所指定的：http://leaflet.cloudmade.com/examples/quick-start.html在div#map上使用样式

<div id="map" style="height: 200px"></div>
