HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
This document appears to be written in Finnish but the “html” start tag has “lang="en"”. Consider using “lang="fi"” (or variant) instead.
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “"true"” for attribute “aria-haspopup” on element “a”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “h2” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “font” element is obsolete. Use CSS instead.
Bad value “'checked'” for attribute “checked” on element “input”.
Attribute “name” not allowed on element “span” at this point.
