Targeting IE7 via an embedded style block

Posted on 2008-06-20

Here's the situation:
I've just been handed a Javascript file which writes a bunch of html to the document via document.write(); . I need to change around this html considerably, and it has to work in *at least* FireFox, Safari, and IE7. I have no access to any file other than this one Javascript file.

As I see it, there are two ways I can include css:
1) Inline via the "style='....'" attribute
2) I can have the Javascript function spit out a <style type='text/css'>...</> block before I have it write my html.

But how do I target IE7 in this situation? I've only really dealt with fixing IE6 bugs, which I did via a Holly Hack. Obviously that won't work with IE7.

Conditional comments do not appear to work within a style block. But I found that the method outlined at the URL below seems to work. That is, using conditional comments to wrap all your html in a div that only IE sees, and then using descendant selectors in your css to generate IE-specific behavior. This makes the IE-targeting syntax in the style block nearly identical to a Holly Hack.

Can anyone verify that conditional comments do or do not work in a style block directly?

>>in a style block directly
Not "in" - "OUT". The conditional comment "Wraps" around your html tag (<link..>,<style...>, or whatever else):

<!--[if IE 7]>
<style type="text/css">

Ok, so I can just do a 2nd, IE-specific, style block after the main one, and re-define any classes I need to in order to target styling specifically to IE....right?

Correct. The conditional comment need to be AFTER the "main" style block.
