Salve, sono nuovissimo e di conseguenza n00bissimo del mondo.
Ad ogni modo preparando un sito, dopo averlo "terminato" mi hanno subito fatto notare gli utenti di safari e IE che non funziona come dovrebbe..

il sito in questione è Questo

e questo è il codice della pagina iniziale (tanto per le altre è sempre uguale )

codice:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>World oF Twilights</title>
<meta name="keywords" content="" />
<meta name="description" content="" />
<link href="default.css" rel="stylesheet" type="text/css" />
<script language="javascript">
<!--

function toggleLayer( whichLayer )
{
  var elem, vis;
  if( document.getElementById ) // this is the way the standards work
    elem = document.getElementById( whichLayer );
  else if( document.all ) // this is the way old msie versions work
      elem = document.all[whichLayer];
  else if( document.layers ) // this is the way nn4 works
    elem = document.layers[whichLayer];
  vis = elem.style;
  // if the style.display value is blank we try to figure it out here
  if(vis.display==''&&elem.offsetWidth!=undefined&&elem.offsetHeight!=undefined)
    vis.display = (elem.offsetWidth!=0&&elem.offsetHeight!=0)?'block':'none';
  vis.display = (vis.display==''||vis.display=='block')?'none':'block';
}

			<h2>IE User, Here</h2>
			<h1>World Of Twilights</h1>
			

World oF Twilights Studio came to life to fulfill your game experiences with Sound Effects and Atmospheres.

Why just drawings and descriptions while the atavistic enemy of your heroes may have a unique and distinctive voice?

What about a secret dungeon door's opening sound to delve your characters IN the scene?

Haven't you hear the chief of the secret agency making a speech with the President of the Confederation behind the studio's door?

And what about the eerie sound of your psychic power filling the air before blasting the glasses in the room and hurling them in your rivals body?</p>


Terrifying aliens and wonderful fairies are now at your disposal, Game Master.</p>


There's only one limit to what can be unleashed...</p>
<p style="padding-left: 200px;">...Your imagination...</p>

			<h1>The Gate Has Been Opened</h1>
			

The site is still WIP, and IE Users won't be very happy, but in a few days everything will be fully operative.
			IE users Here
			

			While you're waiting for the tasty dish, I hope you'll appreciate a little example of what this site will soon provide you

			Walk through a Country Field near animals and horse wagons or feel noisy ambience in a Wrecked Space Station
