See the component page for more information.
Download the element using bower. For that, enter
bower install --save login-box
And the element will be installed and persisted in your bower.json.
Usage is very simple. Just type
<login-box></login-box>and you're good to go!
The element only fires its login-box-login-try event, if both
the identification value and password value are filled. In the event detail,
there is a field identifier and a field password, both should be quite self-
explanatory.
