HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Bad value “https://fonts.googleapis.com/css?family=PT+Sans|Source+Sans+Pro” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “form” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “blockquote”.
Stray end tag “blockquote”.
Bad value “200px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
