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
