Can we use like this <body class="all" <!--[if IE 7]>class="ie"<![endif]--> >?
I want to keep all CSS in one file开发者_如何学运维.
You could use:
<body class="all">
<!--[if ie]>
<div class="ieOnly">
<![endif]-->
<div id="content">
<p>...</p>
</div>
<!--[if ie]>
</div>
<![endif]-->
</body>
That way the css selector to address IE's flaws/differences is more specific than the normal
#content {/* for non-IE browsers */}
body.all .ieOnly #content {/* for IE */}
...and should override the 'normal' #content rules and will never be applied by non-IE browsers, since there's an element .ieOnly in the selector which is otherwise 'invisible' to them.
Still, strictly speaking, no; you can't do what you propose in your question, though there are alternative approaches.
Short answer: No (at least, not in-line), but why do you need to? :)
Just defined a body { } style in an IE conditional stylesheet, like this:
<!--[if IE 7]>
<link rel="stylesheet" type="text/css" href="ie7.css">
<![endif]-->
And inside there:
body { /* or body.all { */
background: pink; /* Pink is pretty!, or green, whatever */
}
No, you cant specifically comment out an attribute even with IE's conditional comments. But there could be other ways of expressing it.
If you want to add a class to body based on the browser without hacks, you're gonna need to use server-side code and UA sniffing.
