Applying Different Css Style For Themes

Hi all,

I am developing an application that uses yiibooster. Since my application has three distinct users with their own pages I wanted to apply three different css.The guest user will have the default yiibooster’s styling but after login I wanted to change the styling of these pages by applying the css files from Bootswatch.As I understand it when using theme in yii,the views will be inserted in the theme’s folder and the theme will be called from config/main.php like ‘theme’=>‘myTheme’. Any ideas on how to go around this.

Thanks in advance
