Jnu.ac.kr HTML Validation

HTML Validation Tool

Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

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 “http-equiv” not allowed on element “meta” at this point.

Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.

Attribute “name” not allowed on element “meta” at this point.

Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.

Bad value “_blank ” for attribute “target” on element “a”: Reserved keyword “blank ” used.

“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.

Bad value “_self ” for attribute “target” on element “a”: Reserved keyword “self ” used.

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

Element “h4” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)

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

Stray end tag “form”.

Table column 2 established by element “td” has no cells beginning in it.

Warnings

The “border” attribute is obsolete.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

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

A table row was 2 columns wide and exceeded the column count established by the first row (1).
