i've been using the <meta http-equiv="X-UA-Compatible" content="IE=edge"> tag ever since it came along, and switching it to EmulateIE6 and EmulateIE7 every now and then to check that my site still looks good in those.
i was under the impression that it if you change it to EmulateIE6 then your site would appear exactly as it does in a normal copy of IE6.
but this week i found out that isn't true. someone who actually does use IE6 sent me a screenshot of my site, and there was quite a lot of stuff out of place.
so does anyone know what this tag actually does? is it a waste of time? or maybe i am using it wrong.
