Meteor for web and mobile

So lets say I want to build an application with Meteor and I want to have the app run as both a web app and as a mobile app. I want the application to look native on mobile devices. At first, it seems like I could just use Ionic or Onsen to achieve this. The problem here, though is that when using those frameworks, the app will look horrendous in a desktop browser.

How can I solve this issue? I want the app to look good in the browser, but look native as a Cordova app.

You can use Material Design which also looks good on desktop, or another option building two apps sharing the same DB. I also suggest taking a look at Framework7 it seems to have the most complete set of components as far as I’ve seen.
