HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Attribute “border” not allowed on element “input” at this point.
Element “style” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
Attribute “ontouchstart” not allowed on element “img” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
