Remarks
With Microsoft Internet Explorer 6 and later, when you use the !DOCTYPE declaration to specify standards-compliant mode, this attribute applies to the HTML element. When standards-compliant mode is not specified, as with earlier versions of Windows Internet Explorer, this attribute applies to the BODY element, not the HTML element.
