This plugin returns the visitors operating system and browser as CSS browser selectors to use in your HTML.

=====================================================
Basic Usage
=====================================================

The following code returns CSS selectors:
{exp:css_browser_selector}

Or you can provide the user agent as a string:
{exp:css_browser_selector agent="Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)"}

Keep in mind that you can use ExpressionEngine's own Referrer module variable {ref_agent}:
{exp:css_browser_selector agent="{ref_agent}"}


=====================================================
Parameters
=====================================================

agent
If empty, ExpressionEngine will use PHP's own $_SERVER['HTTP_USER_AGENT'] variable.


=====================================================
Credits
=====================================================

This is an ExpressionEngine port of Bastian Allgeier's PHP CSS Browser Selector. (Which is then a port of Rafael Lima's JavaScript CSS Browser Selector.)
