HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
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 “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Element “noindex” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “filter-form”.
Duplicate ID “f_date”.
Duplicate ID “to_date”.
Duplicate ID “filter-submit”.
Duplicate ID “fb-root”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
