title: CSS Padding Issue w/ submit button
body: <p>This is a dumb problem but I can't seem to set the padding on a submit button properly. No matter what I input for padding, the width and height of the button never changes. Here is the css: </p>
  
  <pre><code>.green_submit {
  color: #fff;
  background-color: #94c909;
  border-right: 1px solid #6d9307;
  border-bottom: 1px solid #6d9307;
  border-left: none;
  border-top: none;
  padding: 25px;
  }
  </code></pre>
  
  <p>And the HTML:</p>
  
  <pre><code>&lt;input type="submit" class='green_submit' value="Validate" /&gt;
  </code></pre>
  
  <p>Any obvious problems here? How can I manipulate the padding on a submit button?</p>
