Unable To Customize Css For Detail/grid/tableview

I am trying to customize the CSS for my Yii App, and I have found things that talk about changing the config/main.php file to look something like this:

// application components



			// enable cookie-based authentication









	                'cssFile' => Yii::app()->request->baseUrl.'/css/table_and_grid.css',






The issue I’m having is that while the CSS file is added to the header, none of the styling is taking, and I’m wonder why? How can I fix?

In your widgetFactory you configure the cssFile for CGridView, but bootstrap extensions (yiistrap, yiibooster) uses TbGridView.

Which component do you use in your view: CGridView or TbGridView?
