How to integrate JS / CSS only on specified Pages / custom content types I would like embed my module JS / CSS files only in specified cases.
Like on a /url/ or if a custom content type is rendered?
The concept given by Molot is good. Because url can be changed any time.

Still you can add the css and js file using hook_preprocess_page or yourtheme_preprocess_node in your template.php of active theme.

function yourtheme_preprocess_node(&amp;$vars) {
// Add JS &amp; CSS by node type
if( $vars['type'] == "your-node-type") {
drupal_add_js( /* parameters */ );
drupal_add_css( /* parameters */ );
} 


where yourtheme need to be replaced by the name of the your active theme.

Hope it will work for you.
