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?
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]-->
- 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>.
