问题:

I want to use conditional comments to make a DIV appear ONLY in browsers with IE7 or older, like this:

<!--[if lt IE 7]>

<div id="browsernotice">
<p>You are using IE7 or less</p>
</div>

<![endif]-->

As far as I understand, conditional comments only work in the header.

Is this bad?

Should I rather use conditional comments to instert a stylesheet that makes an invisible DIV visibility:visible?

回答1:

The best way is to keep the content as is in the document body but instead apply a style sheet for ie that hides the div.

with css 

    #browsernotice {
       display:none;
}

And call it with a conditional statement 

<!--[if lt IE 7]>
<link href="ie7.css" type="text/css" rel="stylesheet">
<![endif]-->


回答2:

  • Yes, it is bad to put a <div> in your <head>. It's not valid.
  • Conditional comments do work anywhere in the document (where did you get the idea they don't?), so just put your code at the top of your <body>.
