Actually i need to change theme on client basis using angularjs.
So suppose if my client is "ABC" so need to select theme "bootstrap_abc_theme", if my client is "XYZ" then it will select "bootstrap_xyz_theme" like that. Basically i need to provide different theme to each and every one client.
Another solution could be:
ng-href in your
<link> and modify it's variable in your controller.
