Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Attribute “size” not allowed on element “link” at this point.
The “id” attribute on a “map” element must have an the same value as the “name” attribute.
Element “img” is missing required attribute “src”.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The value of attribute “alt” on element “img” from namespace “http://www.w3.org/1999/xhtml” is not in Unicode Normalization Form C.
