Question

I have a basic bootstrap layout with a navbar and a sidebar(span 3) + map(span 9).
My problem is that when i look at this code in the browser the map looks like this: http://dl.dropbox.com/u/15923835/bootstr.jpg

But I want a fixed size for the map (it should cover 80% of the page something. I have tried to set a fixed height in every DIV but nothing happens. Do you have any suggestions?

Sorry for my bad technical explanation (i’m trying to learn)

here’s a copy of the code:

<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>
          <li><a href="#">Link</a></li>
          <li><a href="#">Link</a></li>
          <li><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>
          <li><a href="#">Link</a></li>
          <li><a href="#">Link</a></li>
          <li><a href="#">Link</a></li>
        </ul>

Answer 1

as specified in the quick start : http://leaflet.cloudmade.com/examples/quick-start.html use a style on the div#map

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