HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Stray end tag “source”.
Bad value “” for attribute “src” on element “iframe”: Must be non-empty.
Bad value “true” for attribute “allowfullscreen” on element “iframe”.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “div” not allowed as child of element “strong” 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.
Duplicate ID “SVGID_1_”.
Duplicate ID “elipses_x5F_bases”.
Element “foooter” 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.
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “SVGID_1_” was here.
The first occurrence of ID “elipses_x5F_bases” was here.
This document appears to be written in Portuguese. Consider adding “lang="pt"” (or variant) to the “html” start tag.
