How to add class in title div for specific block? I have created a block using Views module in website using drupal 7.
My block title's HTML structure is as bellow:

&lt;div class="titleHeader clearfix"&gt;
   &lt;h3&gt;BLOCK_TITLE&lt;/h3&gt;
&lt;/div&gt;


I want to add a class in &lt;div&gt;.
Should I create a module for this or any other way?
Please guide me how can I do this?

Thank you in advance
function themename_preprocess_block(&amp;$variables) {

if($variables['block']-&gt;bid == 'views-front-block') {

     $variables['classes_array'][] = 'container';
 }


}

add this function in your template.php file of your theme.
