HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
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 “” for attribute “name” on element “input”: Must not be empty.
Element “input” is missing required attribute “alt”.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Element “style” not allowed as child of element “section” 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.
Stray start tag “html”.
Stray start tag “head”.
Element “title” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
