HTML markup errors and warnings

(Rescan now...)

Errors:

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

Attribute “xmlns:og” not allowed here.

Attribute “xmlns:fb” not allowed here.

When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.

Bad value “Cache-control” for attribute “http-equiv” on element “meta”.

Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Attribute “ref” not allowed on element “link” at this point.

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

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

Bad value “site-header hidden-sm hidden-xs” for attribute “id” on element “div”: An ID must not contain whitespace.

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

Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.

The “center” element is obsolete.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

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:

Attribute with the local name “xmlns:og” is not serializable as XML 1.0.

Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.

Consider avoiding viewport values that prevent users from resizing documents.
