Can I use conditional comments from Chrome Frame?

Using...

<!--[if lte IE 8]> <html class="ie8-7-6"> <![endif]--> .ie8-7-6 .loginForm {display:none;} /* The login form is hidden. */

and

 .ie8-7-6 .yourbrowserisold {display:block;} /* and some nice graphics appear to indicate it doesn't support IE6, 7, or 8. */

So this works very well and I provide a link to download Chrome Frame.

But now, if Chrome Frame is installed, I would like it to be oposite.

 <!--[if CF]><html class="chrome-frame><![endif]--> .chrome-frame .yourbrowserisold {display:none;} .chrome-frame .loginForm {display:block;}

But

 <!--[if CF]><html class="chrome-frame><![endif]-->

doesn't work, and I need a login form.

I have searched for dozens of websites and I cannot find the answer if ...

a. is this even possible with conventions?

b. or is it only possible with javascript?

Any help?

----- Update ---------- Here is a script to determine if Google Frame is installed or not.

 $(document).ready(function() { if( $.browser.chromeframe != window.externalHost) {alert("You are using chrome frame. You rock!"); } else { alert("You are not using chrome frame."); } });

FYI: you can add your own jQuery to the above script for target Chrome Frame users.

The best way to detect that you are in Chrome Frame inside IE is checking

 var isChromeFrame = !!window.externalHost;

This is only available in Chrome Frame. There is currently no conditional construct for comments on Chrome Frame.

More details at http://www.chromium.org/developers/how-tos/chrome-frame-getting-started/understanding-chrome-frame-user-agent .

But to your situation, if the user already has Chrome Frame installed and you start it using the chrome=1 flag, then they will never see the content inside the conditional comments of IE.
