There is some ready/default code to block Internet Explorer 6 or lower versions?

I want show a message to users if t开发者_高级运维hey're using IE6 that the browser is outdated in a div. There is something done to do this?

There exist ready-to-copypaste scripts for that already. E.g. http://www.ie6nomore.com/

You can do it with just CSS

<style type="text/css">
/* Regular/More CSS Info Here
#wrongbroswer { display:none; }
</style>
<!--[if lte IE 6]>
<style type="text/css">
#wrongbroswer { display:; }
</style>
<![endif]-->

You can do it with code, but this is way more fun:

http://ie6update.com/

It gently encourages....ok, tricks....the user to upgrade their browser in a safe looking manner. Shifty? Yes. But SO much fun to get back at Microsoft for all they do to us web guys...
