HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
Element “style” not allowed as child of element “header” in this context. (Suppressing further errors from this subtree.)
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
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 “strong”.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Attribute “href” not allowed on element “div” at this point.
Bad value “30px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
