OS Adder


This plugin adds a abbreviation of the operating system (win, mac, linux, iPad, iPhone) to the body-tag.
So if there’s a OS-specific difference, you can easily react to it by using the css-selector (e.g. “.mac”).

Next steps of this plugin:
* adding a settings page
* add the class to specified elements
* add user-language-abbreviation to specified elements

let me know, if you wish something helpful.


  • added Class


  1. Upload OS Adder to the /wp-content/plugins/ directory or access it via the wordpress plugin site
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. You’re done.


Does the added Class also tell me if it’s a 32 or 64 bit OS?

No, it’s just “win”, “mac”, “linux”, iPad, iPod, iPhone or “os-unknown”.
When it’s a “Linux armv7l”-machine, the plugin outputs “android”.
