Add/Remove CSS Class to any element using JQuery

Below code will apply the CSS class to a tag element using JQuery. You can download the Jquery from http://docs.jquery.com/Downloading_jQuery

 <style type="text/css">
        .color
        {  
            color: Red;
           font-weight: bold;
        }
 </style>

<script type="text/javascript" src="Script/jquery-1.3.2.js"></script>

<script type="text/javascript">
              $(document).ready(function(){
               $("#hypDotnetFunda").addClass("color");
});
</script>

Here is a tag with hypDotnetFunda ID.

<a id="hypDotnetFunda" href="http://www.dotnetfunda.com/default.aspx">DotnetFunda</a>

Same way you can also remove the class using removeClass() method.

<script type="text/javascript">
   $(document).ready(function(){
    $("#hypDotnetFunda").removeClass("color");
});
</script>

Enjoy..
