Is there a CSS media query to detect Windows?

I want to specify two slightly different background colors, one for Mac OS, one for Windows.

there is no property to specify OS used to view webpage, but you can detect it with javascript, here is some example for detecting Operating system :

var OSName="Unknown OS";
if (navigator.appVersion.indexOf("Win")!=-1) OSName="Windows";
if (navigator.appVersion.indexOf("Mac")!=-1) OSName="MacOS";
if (navigator.appVersion.indexOf("X11")!=-1) OSName="UNIX";
if (navigator.appVersion.indexOf("Linux")!=-1) OSName="Linux";

console.log('Your OS: '+OSName);

got it?, now you can play with document.write
to write download stylesheet for specific Operating system. :)

another example, i assumed that you are using jquery.

if (navigator.appVersion.indexOf("Win")!=-1) 
} else {
  $(body).css('background','#000'); // this will style body for other OS (Linux/Mac)

Older versions of Firefox could also detect windows (for those who are not using autoupdate) and are using version 4 or newer. It is more basic and does not tell the version, just the fact you are in windows. I created this one for testing a while back because I was curious.

@media screen and (-moz-windows-theme) {
    body {
        background-color: white;

this is also covered in

In CSS, not possible. At most there’s a @media
filter so you can target mobile devices v.s. desktop devices, but there’s no @os
type filter.

You can achieve it with IE’s conditional tags:

Put the mac-specific styles into the ‘everyone’ css, and then override whatever’s necessary in the IE version.

Of course, this will fail if you get a user who’s on an (ancient) IE for Mac version, but should cover all modern users.

it is available in the latest mozilla version.

-moz-os-version provides following values:

  • windows-xp
  • windows-vista
  • windows-win7
  • windows-win8

support is limited

@media (-moz-os-version: windows-xp), (-moz-os-version: windows-vista),
(-moz-os-version: windows-win7), (-moz-os-version: windows-win8) {
        background-color: white;
