title: Set width of text input form with blueprint
body: <p>I try to layout a form composed by a label and a text input. I want to set the width of the input element because the default is too wide.</p>
  
  <pre><code>&lt;div class="container"&gt;
      &lt;div class="span-24 last"&gt;
          &lt;label for="age"&gt;Age: &lt;/label&gt;
          &lt;input class="text span-2"/&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I tried to use <code>span-2</code> but the input text is displayed before the label.</p>
