Errors:

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

No space between attributes.

Text not allowed in element “select” in this context.

Duplicate ID “nav-menu-item-5”.

End tag “li” seen, but there were open elements.

Unclosed element “div”.

Duplicate ID “nav-menu-item-109”.

Duplicate ID “nav-menu-item-119”.

Element “form” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)

Stray end tag “ul”.

The “font” element is obsolete. Use CSS instead.

Garbage after “</”.

End tag “div” seen, but there were open elements.

Unclosed element “small”.

Element “ul” not allowed as child of element “small” in this context. (Suppressing further errors from this subtree.)

CSS: “font-size”: only “0” can be a “unit”. You must put a unit after your number.

Element “div” not allowed as child of element “small” in this context. (Suppressing further errors from this subtree.)

End tag “section” seen, but there were open elements.

Element “section” not allowed as child of element “small” in this context. (Suppressing further errors from this subtree.)

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)

Stray end tag “div”.

End tag for “body” seen, but there were unclosed elements.

Warnings:

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

The first occurrence of ID “nav-menu-item-5” was here.

The first occurrence of ID “nav-menu-item-109” was here.

The first occurrence of ID “nav-menu-item-119” was here.

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

The “charset” attribute on the “script” element is obsolete.

The “language” attribute on the “script” element is obsolete. You can safely omit it.

The “type” attribute is unnecessary for JavaScript resources.

Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
