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”.
CSS: “filter”: “"alpha(opacity=0)"” is not a “filter” value.
CSS: “filter”: “"alpha(opacity=100)"” is not a “filter” value.
CSS: “visibility”: “transparent” is not a “visibility” value.
CSS: “box-sizing”: “box-model” is not a “box-sizing” value.
Attribute “http-equiv” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Element “style” not allowed as child of element “noscript” in this context. (Suppressing further errors from this subtree.)
Stray start tag “head”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Element “option” without attribute “label” must not be empty.
Stray end tag “head”.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
