title: How to create textbox with fixed label in Material Design Lite?
body: <p>When I was reading the documentation in Material Design Lite's official page, no class name is mentioned for the fixed label with a textbox. In case of textarea they have a solution. But same code like the following one is creating only placeholder instead of a label for <code>input type = "text"</code>.</p>
  
  <pre><code>&lt;div class="mdl-textfield mdl-js-textfield"&gt;
      &lt;input class="mdl-textfield__input" type="text" id="sample5"&gt;
      &lt;label class="mdl-textfield__label" for="sample5"&gt;Text lines...&lt;/label&gt;
    &lt;/div&gt;
  </code></pre>
