HTML markup errors and warnings
(Rescan now...)
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad start tag in “img” in “head”.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Element “dl” is missing a required child element.
Bad value “” for attribute “src” on element “source”: Must be non-empty.
Stray end tag “source”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “description” not allowed on element “div” at this point.
Element “div” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Empty heading.
