IE 9 Conditional Comment

Legacy Dynamo
1

Is there something different about IE 9 with regard to conditional comments? I can’t get mine to work.

<!--[if IE 9]>
	<link rel="stylesheet" type="text/css" media="screen" href="/css/ie9.css"/>
<![endif]-->

what about the leading slash on /css/ie9.css ?? if the css folder is the
same level as the html file, then no slash, right? and if above the current
folder then two dots first, as …/css/ie9.css ???

The thing is if I target IE8 or 7 using the same syntax it works. I’ll try your suggestion.

Thanks

I’m probably wrong… the leading slash seems to be something called a
“root-relative” path and should be the equivalent of calling a document at
the same level.

Is there a problem at the css file? Maybe it’s the css code’s not working?
Me just guessing.

A reasonable guess and one that I considered but even the most basic of CSS doesn’t work. It seems I’m not alone in this as I’ve found many others who have had problems with v9 and CC. Curious.

Hi Todd,
This thread on Stack Overflow may help;

It looks like IE 9 contains a bug (who would have thought it?) where conditional comments with no leading space are ignored. It appears you can either add the space or set the content type of the page and the comment should work again.
Regards,
Tim.

That stackoverflow post is misleading, see the Answer (and my comment
in the Question.) It appears that the one who asked the question failed
to add the ! - in the <![endif]–>, which in turn explains why adding
the space helps …

I am not able to replicate the problem.

I would suggest that Todd sends us a link to a page which demoes the
problem that he experience.

Hi Leif & Tim,

I also found that post yesterday and Leif is correct, though I tried just to be sure. No luck. I’ll put an example online when I have a moment.

Thanks to you both.

The only way (I think) I can replicate this is if I press the
Compatibility View button in IE9.

The effect of the compatibility view button can be replicated with the
F12 Developer Tools: Just select Browser Mode IE9 Compatibility View.

As much as I understand, a Web page cannot force the Compatibility View

  • this has to be done by the user. So if you have the F12 Developer
    tools installed, have you verified that this is not something only you,
    the developer, see?

I think I figured it out. Turns out it was my CSS syntax. The same CSS that works fine in IE7 and 8 CC didn’t work in 9 so it was a simple fix.

Thanks,

Todd
