Is Angular 4 material responsive like bootstrap?

A bit late but I have created a starter template that shows an example of a responsive layout with Material 5 and Angular 5 as well as some simple routing. https://github.com/kenji-1996/material-sidenav-responsive-starter

Uses Material and Flex, no outside libs

To add responsiveness in modern angular app you can use Flex-layout it is completely separate from material2 so you can use that even without using material2 in your app.

Bare in mind that as flex-layout is based on Flexbox CSS so it is not supported in old browsers.

Here are some examples

Also check out the new ngAir episode episode talking about Flex-Layout

UPDATE:

Starting from 6.0.0-beta.16 flex-layout now has an API to support CSS Grid. You can find more details by checking pr#712
