Snippets by IsItWP

Are you looking for a way to detect the user’s browser to use browser targeted styles? This snippet provides a unique way of detecting the browser so that you can apply special styling for certain browsers.

Instructions:

  1. Add this code to your theme’s functions.php file or in a site-specific plugin.
  2. <?php
    add_filter('body_class','browser_body_class');
    function browser_body_class($classes) {
    	global $is_lynx, $is_gecko, $is_IE, $is_opera, $is_NS4, $is_safari, $is_chrome, $is_iphone;
    	if($is_lynx) $classes[] = 'lynx';
    	elseif($is_gecko) $classes[] = 'gecko';
    	elseif($is_opera) $classes[] = 'opera';
    	elseif($is_NS4) $classes[] = 'ns4';
    	elseif($is_safari) $classes[] = 'safari';
    	elseif($is_chrome) $classes[] = 'chrome';
    	elseif($is_IE) $classes[] = 'ie';
    	else $classes[] = 'unknown';
    	if($is_iphone) $classes[] = 'iphone';
    	return $classes;
    }
    ?>
    
  3. A class with the name of the browser will be added to your body classes, like this:
    
    <body class="home blog logged-in ie">
    
    

    You can then create styles for the browsers you want to target. For example, for Internet Explorer you would use the .ie class:

    
    body.ie #mydiv {
      /* Here goes IE fix */
    }
