title: Styling a submit button using zend form
body: <p>Currently my button is used in a Zend form, I can work out how to add tags etc. but nothing I am doing at the minute with either the HTML or the CSS is giving it any results.</p>
  
  <p>My code for the button is below:</p>
  
  <pre><code>class Application_Form_Newsletter extends Zend_Form
  {
      public $processed = false;
  
      public function init()
      {
          $this-&gt;addElement(
              'text', 'email', array(
                  'label' =&gt; '',
                  'required' =&gt; true,
                  'validators' =&gt; array(
                  array('StringLength', false, array('max'=&gt;150)),
                  'EmailAddress',
                  ),
              )
          );
  
          $this-&gt;addElement('submit', 'go', array(
  
              'id'=&gt;'btnNewsletter',
              'type'=&gt;'image',            
            ));
      }
  }
  </code></pre>
  
  <p>The style sheet code is a follows:</p>
  
  <pre><code>#btnNewsletter{ background-image: url('../img/home-search-background-btn.png');}
  </code></pre>
  
  <p>I've managed to get the image to display but it is always hidden behind the actual button itself.</p>
