Effects of using $routeProvider for routing

I am using AngularJS 1.2.21.

As long as I am using NodeJS with Express for routing for serving ejs pages, everything works fine, but if once I start using $routeProvider for routing using ng-view, some of the CSS and jQuery doesn't seem to work properly.

For example: css style for checkbox is gone and the default checkbox of the browser overrides and jQuery RateIt plugin stops working.

Could somebody help me understand why it might be happening?
