title: HTML: Giving image map area color
body: <p>I have a file where a map image ("worldmap.jpg") is displayed, on which there is a clickable area ("Site_1"):</p>
  
  <pre><code>&lt;img src="worldmap.jpg" width="1425" height="1296" alt="World" usemap="#worldmap"&gt;      
  
  &lt;map name="worldmap"&gt;           
      &lt;area shape="circle" coords="350,320,50" alt="Site_1" href="site1.htm"&gt;
  &lt;/map&gt;
  </code></pre>
  
  <p>Is there a way to make the clickable area visible (that is, make the circle green)? </p>
