title: Changing the color of the Span
body: <p>I am a beginner in learning Jquery.
  I tried a simple sign up form in jquery. 
  here,if the username and password is not entered in the text box then a label is displayed with span saying"Please fill the username".
  How to change the span font color? 
  Here is my code:</p>
  
  <pre><code>if(user=="") { 
   $('#dis').slideDown().html("&lt;span&gt;Please type Username&lt;/span&gt;");
   return false; 
  } 
  </code></pre>
  
  <p>Thank you...</p>
