title: How to make the search form without the search button?
body: <p>This question is related to CSS/HTML and drupal web development. I am developing website using Drupal 7. And by default <code>Drupal</code> provides the <code>Search form</code> (as shown in image) with input text box and button next to it. How can I remove the that search button and make it like just text input box, for example you can see the <code>search form</code> of <code>stackoverflow</code>. So by this there is no need for clicking the button, just write text and enter. Thanks</p>

  <p>Note: Drupal is the content management system. And why I am asking this question here as solution is related to CSS/HTML. </p>
