Fit page to screen size

If I run the vaaddion dashboard (https://demo.vaadin.com/dashboard/) on my mobile phone (Black Berry) the login screen fills up the complete screen.

I also developed a login screen (similar to the dashboard), but it only shows the the components very small on the top of the screen. There is a bug not used space below. Is there a possibility to adapt the components (font size, component size, …) to the screen resolution?

Thanks in advance!

If I understood correctly you need to set the meta tag viewport
https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag
. Take a look at an example here:
