@maruru makes a great point. If the application is a simple one, you could easily use vanilla javascript. You could use es6 template literals to render your UI. You could use Fetch API instead of AngularJS' $http or $resource. Again, like Marco said, you could also easily implement responsiveness with flexbox. If you didn't want to do that, a cheap alternative could be to use a lightweight css framework. Something like Bulma would work great for this.
On the other hand, since it is a small project, you could use it as an opportunity to build it in a new framework just for the experience. Just a thought
