title: Bootstrap columns not appearing inline
body: <p>I'm new to bootstrap and CSS in general. I have some html which looks like this:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
    &lt;head&gt;
      &lt;meta charset="utf-8"&gt;
      &lt;title&gt;My Site&lt;/title&gt;
      &lt;link rel="stylesheet" href="/css/bootstrap-theme.css"&gt;
      &lt;link rel="stylesheet" href="/css/font-awesome.css"&gt;
    &lt;/head&gt;
    &lt;body&gt;
      &lt;div class="container"&gt;
        &lt;div class="row"&gt;
          &lt;div class="col-md-1"&gt;&lt;span class="fa fa-caret-down"&gt;&lt;/span&gt;&lt;/div&gt;
          &lt;div class="col-md-1"&gt;&lt;span id="cool-title"&gt;My Site&lt;/span&gt;&lt;/div&gt;
          &lt;div class="col-md-1"&gt;
            &lt;input type="text" placeholder="Search" class="search-bar"&gt;
          &lt;/div&gt;
          &lt;div class="col-md-1"&gt;
            &lt;button class="btn btn-default"&gt;&lt;i class="fa fa-search col-md-1"&gt;&lt;/i&gt;&lt;/button&gt;
          &lt;/div&gt;
        &lt;/div&gt;
        &lt;div id="main"&gt;
        &lt;/div&gt;
      &lt;/div&gt;
      &lt;script src="/js/jquery.js"&gt;&lt;/script&gt;
      &lt;script src="/js/bootstrap.js"&gt;&lt;/script&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I want all of those <code>col-</code> divs to be inlined, but they are all showing up on their own rows:</p>

  <p>What's going on here?</p>
