HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “Expires” for attribute “http-equiv” on element “meta”.
Bad value “Pragma” for attribute “http-equiv” on element “meta”.
Bad value “previewimage” for attribute “rel” on element “link”: The string “previewimage” is not a registered keyword.
Bad value “X-XRDS-Location” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “h2” seen, but there were open elements.
Unclosed element “span”.
