title: Bootstrap 3.3.0 and Visual Studio 2012
body: <p>like <a href="https://stackoverflow.com/a/26696078/2401823">here</a> I tried to update "Microsoft ASP.NET Web Optimization Framework" but It doesn't solve my problem: I get a index out of range in </p>
  
  <pre><code>@Styles.Render("~/Content/css")
  </code></pre>
  
  <p>for <em>bootstrap.css</em>. If I delete the following rules:</p>
  
  <pre><code>_:-ms-fullscreen,
  :root input[type="date"],
  _:-ms-fullscreen,
  :root input[type="time"],
  _:-ms-fullscreen,
  :root input[type="datetime-local"],
  _:-ms-fullscreen,
  :root input[type="month"] {
      line-height: 1.42857143;
  }
  
      _:-ms-fullscreen.input-sm,
      :root input[type="date"].input-sm,
      _:-ms-fullscreen.input-sm,
      :root input[type="time"].input-sm,
      _:-ms-fullscreen.input-sm,
      :root input[type="datetime-local"].input-sm,
      _:-ms-fullscreen.input-sm,
      :root input[type="month"].input-sm {
          line-height: 1.5;
      }
  
      _:-ms-fullscreen.input-lg,
      :root input[type="date"].input-lg,
      _:-ms-fullscreen.input-lg,
      :root input[type="time"].input-lg,
      _:-ms-fullscreen.input-lg,
      :root input[type="datetime-local"].input-lg,
      _:-ms-fullscreen.input-lg,
      :root input[type="month"].input-lg {
          line-height: 1.33;
      }
  </code></pre>
  
  <p>it works. It's a "Microsoft ASP.NET Web Optimization Framework" bug or what?</p>
