HTML markup errors and warnings
(Rescan now...)
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”.
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Empty heading.
Unsupported SVG version specified. This validator only supports SVG 1.1. The recommended way to suppress this warning is to remove the “version” attribute altogether.
