title: Radio button is not working properly
body: <p>In my web page I have placed some radio buttons. But these buttons are not working properly. I can check multiple buttons.</p>
  
  <p>code:</p>
  
  <pre><code>&lt;label for="abc" style="margin-top:-20px;margin-left:40px"&gt;xyz&lt;/label&gt;
  &lt;input type="radio" id="abc" name="abc" &gt;        
  &lt;label for="bcd" style="margin-top:-20px;margin-left:40px"&gt;abc&lt;/label&gt;
  &lt;input type="radio" id="bcd" name="bcd" &gt;
  &lt;label for="efg" style="margin-top:-20px;margin-left:40px"&gt;ccc&lt;/label&gt;
  &lt;input type="radio" id="efg" name="efg" &gt;
  </code></pre>
