Consider the following HTML:

1. <div id="jjTechSol" style="height: 50px;width: 50px;">
2.  <p>Content</p>
3.  </div>

The following jQuery is used to get the value of a CSS property.

1. <script type="text/javascript">
2. $(document).ready(function () {
          alert('Height:'+$("#jjTechSol").css('height'));
3.        alert('Width:'+$("#jjTechSol").css('width'));
   });
4. </script> 

.css( propertyName ) gets the value of style properties for the first element in the set of matched elements.

     propertyName
     Type: String    
     A CSS property.
