how to use polymer starter kit doc & demo offline?

i have installed polymer starter kit 1.3.0, Using gulp serve i can access index.html located in app folder at localhost:5000.

i have two questions.

1) My question is how to access pre-developed components located at /bower-components/ on web browser?

i have tried to install and serve gulp in /bower-components/,but it still serve the /app/index/

i am not able to access components references on web browser.

2) After complete development how to host it without gulp, ex. on xampp?
