CONDITION CSS区分IE6到IE7

i want to declare a style different to ie6 and ie7 , but my condition in css recognized by IE7 as IE6. I use XP and explorer 7. This the code i use :

我想声明一个与ie6和ie7不同的样式,但我在css中的条件被IE7识别为IE6。我使用XP和资源管理器7.这使用的代码:

<!--[if !IE]>

#mainDiv{text-align:-moz-center;}

#skyBanner {top:0px;left:0px; position:fixed;visibility:hidden;}

<![endif]-->     

<!--[if lt IE 7]>

body > #skyBanner {  position: fixed;}

#skyBanner {position:absolute;visibility:hidden;

left: expression( ( 0 + ( ignoreMe2 = document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft ) ) + 'px' );

top: expression( ( 0 + ( ignoreMe = document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop ) ) + 'px' );

}

<![endif]-->

<!--[if IE 7]>

#skyBanner {position:fixed;visibility:hidden;

}    
<![endif]-->

what is my mistake?

我的错是什么?

You can't use conditional comments in CSS. Only in HTML. So you'd have to put the declarations for the different browsers into different files and conditional-comment several <link>s to them.

您不能在CSS中使用条件注释。仅限HTML。因此,您必须将不同浏览器的声明放入不同的文件中,并对其中的几个进行条件注释。

So more something along the lines of

所以有更多的东西

<html>
  <head>
    <!--[if !IE]>
      <link rel="stylesheet" type="text/css" href="style_non_ie.css">
    <![endif]-->
    ...
  </head>
</html>

Your !IE is incorrectly commented, and you are missing style tags. If this is exactly how it exists in your HTML then that is your problem. If this is in a CSS file then you cannot use conditional comments in that location.

您的IE浏览器评论错误,您缺少样式标记。如果这正是HTML中存在的那么,那就是你的问题。如果这是在CSS文件中,那么您不能在该位置使用条件注释。

Corrected:

<!--[if !IE]>-->
<style type="text/css" media="screen">
    #mainDiv {text-align:-moz-center;}
    #skyBanner {top:0px;left:0px; position:fixed;visibility:hidden;}
</style>
<!--<![endif]-->

<!--[if lt IE 7]>
<style type="text/css" media="screen">
    body > #skyBanner {  position: fixed;}
    #skyBanner {position:absolute;visibility:hidden;
    left: expression( ( 0 + ( ignoreMe2 = document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft ) ) + 'px');
    top: expression( ( 0 + ( ignoreMe = document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop ) ) + 'px' );
    }
</style>
<![endif]-->

<!--[if IE 7]>
<style type="text/css" media="screen">
    #skyBanner {position:fixed;visibility:hidden;}
</style>
<![endif]-->

Again, as it is currently written, NO browser is seeing the !IE code.

再次,正如目前所写,没有浏览器看到!IE代码。

I'm also not sure you've written the other conditionals correctly. You have "body > #skyBanner {position: fixed;}" under the "if lt IE 7" conditional, yet IE6 and lower do not support this CSS selector to my knowledge.

我也不确定你是否正确地编写了其他条件。您在“if lt IE 7”条件下有“body> #skyBanner {position:fixed;}”,但IE6及更低版本不支持我的CSS选择器。

So any number of the issues I've described could be leading to your problems with IE6 and IE7.

因此,我所描述的任何问题都可能导致您对IE6和IE7的问题。

You need to do it a bit different way. Use comments and enclose links to browser specific CSS files. This way it should work:

你需要做一些不同的方式。使用注释并将链接附加到浏览器特定的CSS文件。这样它应该工作:

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

<!--[if lt IE 7]>
<link href="IE6.css" rel="stylesheet" type="text/css">
<![endif]-->

<!--[if IE 7]>
<link href="IE7.css" rel="stylesheet" type="text/css">
<![endif]-->

You can also use <style> tags instead of links, but this is a bad way of doing this.

您也可以使用
