HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=ISO-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Duplicate ID “banner_top”.
Element “input” is missing required attribute “alt”.
Element “h2” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “ul” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “hr” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Warnings:
The first occurrence of ID “banner_top” was here.
This document appears to be written in Portuguese. Consider adding “lang="pt"” (or variant) to the “html” start tag.
