HTML markup errors and warnings
(Rescan now...)
Errors:
Attribute “href” not allowed on element “span” at this point.
Attribute “tyle” not allowed on element “script” at this point.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Stray doctype.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “ugc-content"” not allowed on element “img” at this point.
Stray end tag “span”.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
Element “h3” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Attribute “ugc-content"” is not serializable as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Empty heading.
