Q:

Polymer starter kit project showing empty web page

I have created my first polymer-cli project using "polymer-2-starter-kit" and project is successfully created but after serving and opening it in browser it just shows an empty screen both on opera and chrome.
UPDATE
following are errors I can see in the console.

A:

Your bower components are missing. 
You have to install the components as well.
Just do bower install and your project will work.
