title: Get the height of top div and place that value as a top padding of another DIV
body: <p>I am using header div as a fixed header but the height of that div will change on regular basis because the matter comes dynamically. Now the next div which is just below to it was shown when padding top is given to that div.</p>
  
  
  
  
  
  <p>so that the content DIV will also change its position as the height of the header div changes.</p>
  
  <p>I will be greatful if any one can give the code.</p>
