title: Make one div visible and another invisible
body: <p>I have two div tags, one is for the search and the other is for the results. What I need is for when the submit button is clicked the results are returned and placed into the results div (with an iframe) and the search div should become hidden and the results div should be made visible.</p>
  
  <p>search div is initially set to visible (using the visibility to visible) and the results div is initially set to hidden (using the visibility to hidden).</p>
  
  <p>Also, initially ther eis a huge white space at the bottom of the page where the hidden div is, so how do I make sure there is no extra white space at the bottom too.</p>
