HTML markup errors and warnings
(Rescan now...)
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.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
No “p” element in scope but a “p” end tag seen.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Bad value “https://www.g-store.ru/ad/?phrase=GA-700UC-3A,GA-500-1A, EQB-700D-1A, PRW-3100-1E,PRG-600YB,GST-W300-1A” for attribute “src” on element “iframe”: Illegal character in query: space is not allowed.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
Bad value “450px” for attribute “height” on element “iframe”: Expected a digit but saw “p” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
End tag “footer” seen, but there were open elements.
Unclosed element “div”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Empty heading.
