title: Sliding searchbox with full page overlay effect
body: <p>I would like implement on my own website this kind of search box (click on "cerca" in the top menu): <a href="http://www.solidstudio.it/#" rel="nofollow">http://www.solidstudio.it/#</a>.</p>
  
  <p>How works this sliding horizontal effect on click to display the searchform combined with the fullpage overlay effect? </p>
  
  <p>Do you know some tutorials for this or could you help me to build? </p>
  
  <p>Thank you so much in advance, 
  Démian P.</p>
