Errors:
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Bad value “ ” for attribute “href” on element “a”: Must be non-empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “dl” is missing a required instance of child element “dd”.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
