HTML markup errors and warnings
(Rescan now...)
Errors:
Bad start tag in “img” in “head”.
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 “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value “” for attribute “width” on element “img”: The empty string is not a valid non-negative integer.
Attribute “async” not allowed on element “link” at this point.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
