title: How to center a button in Material-UI
body: <p>I couldn't figure out how to center buttons in Material-UI. This is the code I have:</p>
  <pre><code>function BigCard(props) {
      const { classes } = props;
      return (
      &lt;div&gt;
          &lt;Card className={classes.card}&gt;
          &lt;CardContent&gt;
              &lt;Typography variant=&quot;display1&quot; className={classes.title}&gt;
              Start Funding!
              &lt;/Typography&gt;
          &lt;/CardContent&gt;
          &lt;CardActions &gt;
              &lt;Button size=&quot;small&quot; color=&quot;primary&quot; className={classes.actions}&gt;
              Share
              &lt;/Button&gt;
              &lt;Button size=&quot;small&quot; color=&quot;primary&quot;&gt;
