Browser & OS as body class

Question

I would like to have the OS and the Browser in the body class. I need that for pixelperfect styling, because the fonts do not behave the same way in different OS / Browser c

You could use regex, but it wouldn't make it any prettier.

Basically, scanning user agent strings for browser/os/version is never going to be beautiful.

Here is something a little prettier with jQuery...

// Add some classes to body for CSS hooks

// Get browser
$.each($.browser, function(i) {
    $('body').addClass(i);
    return false;  
});


// Get OS
var os = [
    'iphone',
    'ipad',
    'windows',
    'mac',
    'linux'
];

var match = navigator.appVersion.toLowerCase().match(new RegExp(os.join('|')));
if (match) {
    $('body').addClass(match[0]);
};

This doesn't quite give you the same classes as above, but enough to differentiate different OS and browser.

For example, you could target Firefox on Windows with...

body.windows.mozilla {
    background: blue;
}

See it!

Or use a plugin.
