I am coding in Yii.

I have registered the main.css file in my main.php layout file like so :

Yii::app()-&gt;clientScript-&gt;registerCssFile($this-&gt;assetsBase.'/css/main.css');


Now this script is being registered in all the pages. However, say I don't want that script to be registered on a specific page.

I know that using : 

Yii::app()-&gt;clientScript-&gt;reset();


would remove all the CSS files, however I want only few CSS files to be unregistered.

Is there a way to do it?
