title: How to style the React google map marker using the given image file
body: <p>Now I am using React-google-map component and want to change the marker to my own image. At this moment, I can't change the size of the marker using CSS.
  I've tried as follows:</p>
  
  <pre><code>var image = {
      url: '../images/icons/yellow.png',
      size: 10
  };
  
  return (
      &lt;Marker 
          position={location}
          icon={image}
          onClick={this.handleMarkerClick.bind(this, marker)}
      /&gt;
      );
  </code></pre>
  
  <p>If you know the solution, please kindly let me know.</p>
  
  <p>Thanks for your help in advance.</p>
