<meta http-equiv = "X-UA-Compatible" content = "IE = EmulateIE7" / "> Where should this be the place in the <head> to render properly in IE7 in IE8?
Having seen that this meta tag changes the way the document is rendered and can cause visual changes, I would apply the same rule as for the content-type header, which is <head> as early as possible .
From the W3C coding specification :
A META declaration should only be used when the character encoding is organized so that ASCII-based bytes denote ASCII characters (at least until the META element is parsed). META declarations should appear as early as possible in the HEAD element.
