title: Can Material-UI be used with Bootstrap 4
body: <p>I am planning to build a React app using Bootstrap-4 and <a href="https://github.com/reactstrap/reactstrap" rel="noreferrer">reactstrap</a> (for the React Bootstrap 4 components) but I would also like to incorporate Google's material design into my app which reactstrap does not provide.
  My question is: could I use Material-UI with Bootstrap 4 instead of reactstrap? This way I would get the React components and also the material design.</p>
  
  <p>Update (26/05/2017): <a href="https://material-ui-1dab0.firebaseapp.com/" rel="noreferrer">Material-UI</a> will soon be releasing their own grid system built with Flexbox.</p>
