Is there a simple conditional statement, css command, html, jquery, javascript or simple PHP dynamic way of detecting the current browser?

With CSS there is no way you can achieve browser detection.
However with PHP, ASP and other programming languages you can get browser detection within the page. I am not here to tell you the pro or cons about it - I take it you know about the bad and good about browser detection and web standards but here is the list.

PHP solution.

if(isset($_SERVER['HTTP_USER_AGENT'])){
    $agent = $_SERVER['HTTP_USER_AGENT'];
}


Then, compare it to what you want

For compare with, for example "firefox" you should do:

if(strlen(strstr($agent,"Firefox")) > 0 ){      
    $browser = 'firefox';
}
if($browser=='firefox'){
    echo '
