My first ever wordpress plugin to find Browser and Operating System on which website is running. It will add those particular names in body tag class attributes as shown below:
<body class=”…. browser-firefox os-windows”>
<body class=”…. browser-chrome os-apple”>
<body class=”…. browser-safari os-iphone”>
<body class=”…. browser-chrome os-android”>
You can configure names as per your need.
You can get this plugin at https://wordpress.org/plugins/browser-and-operating-system-finder/
you can just search for “Browser and Operating System Finder” in search plugins box.
