Warning 1 IE conditional comment was detected. The use of IE conditional comments is discouraged. IE conditional comments work in IE5 to IE9 but support for them has been removed in IE 10 for standards and quirks mode (but not removed for compatibility view). An example of an IE conditional comment is <!--[if IE 9]> ... <![endif]-->. Visit https://msdn.microsoft.com/en-us/library/hh801214(v=vs.85).aspx for more information.
