HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “0;URL=/toolwebv3/enable-javascript” for attribute “content” on element “meta”: Expected a space character, but saw “U” instead.
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Element “style” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)
Element “h3” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value “1” for attribute “border” on element “img”: Only “0” is a permitted zero literal.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
Empty heading.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
