Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:v” not allowed here.
Stray end tag “meta”.
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.
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Duplicate ID “header_charts”.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Duplicate ID “container”.
The “align” attribute on the “table” element is obsolete. Use CSS instead.
The “width” attribute on the “table” element is obsolete. Use CSS instead.
The “width” attribute on the “td” element is obsolete. Use CSS instead.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Bad value “” for attribute “size” on element “input”: The empty string is not a valid positive integer.
The element “button” must not appear as a descendant of the “a” element.
Stray start tag “script”.
Cannot recover after last error. Any further errors will be ignored.
