top of the web page cuts off
===

I have a problem with browser cutting off top of the web pages. It seems working fine on a normal screen, but on a smaller screen like a laptop the top cuts off, but when I refresh the page than it looks fine. 

    <style type="text/css">
    #background {
      width:100%;
      height:100%;
      background-color:#EB9100;
      z-index:-1;
      overflow:auto;
      }
    </style>




  
How would i fix this? Is there way to make my webpage to look the same on any browser or screen size

Thanks!
