HTML markup errors and warnings
(Rescan now...)
Errors:
Unsupported character encoding name: “none”. Will sniff.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “font” at this point.
The “font” element is obsolete. Use CSS instead.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
Attribute “"” is not serializable as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
