HTML markup errors and warnings
(Rescan now...)
Errors:
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 “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Stray end tag “script”.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
Attribute “<div” not allowed on element “div” at this point.
The “center” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “aside” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “slider3”.
Stray end tag “section”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
Warnings:
Attribute “<div” is not serializable as XML 1.0.
The first occurrence of ID “slider3” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
