How to set 3 div's to fit the screen width

Question

Hi all I have problem with my div's in html. I have set them correctly in chrome but when I am using firefox or IE my last div is going in the next row.

Here is my code:

<div id="container">
    <div id="header"></div>
    <div id="left"></div>
    <div id="menu"></div>
    <div id="vis"></div>
    <div id="footer"></div>
<div>

And their css:

body 
{ 
 height: 100%; 
 margin: 0; 
 padding: 0 ;
 border: 0 none;
}
#left
{
background-color:#EEEEEE;
height:570px;
width:73.9%;
float:left;
}
#menu
{
background-color:#D4EAE4;
color:#535353;
height:570px;
width:15.25%;
float:left;
margin:0;
}
#vis
{
background-color:#D4EAE4;
 float:left;
 width:11%;
 height:570px;
 margin:0;
}
#container
 {
 width:98%;
 padding-left:1%;
 padding-right:1%;
 }
#header
 {
 background-color:#4671D5;
 -moz-border-radius-topleft: 100px 50px;
  border-top-left-radius: 100px 50px;
  -moz-border-radius-topright: 100px 50px;
  border-top-right-radius: 100px 50px;
 }

How can I make this div's to fit to each other perfectly in other browsers too? Chrome is exactly what I need. Safari gives me gap between vis and menu of 2px and IE and Firefox is putting my last div vis in the new row. Header and footer are okay. I just put them so you can test it at your pc. And I want to have % as I want this to be usable to all resolutions.

Change menu css to

#menu 
{ 
background-color:#D4EAE4; 
color:#535353; 
height:570px; 
width:15.1%;//previos 15.25% 
float:left; 
margin:0; 
}
