title: How do I use MUI's shadows?
body: <p>I would like to add a shadow to a <code>&lt;Grid container&gt;</code> component.</p>
  <p>I see in the documentation <a href="https://mui.com/system/shadows/#main-content" rel="nofollow noreferrer">here</a>. I should just use something like <code>boxShadow={1}</code> and import <code>import { shadows } from '@material-ui/system';</code>.</p>
  <p>I've done this, but am not getting any results.</p>
  <p>Would anyone know the correct way to add shadows to a component?</p>
