Errors:
Legacy encoding “shift_jis” used. Documents must use UTF-8.
The only allowed value for the “charset” attribute for the “meta” element is “utf-8”.
Bad value “imagetoolbar” for attribute “http-equiv” on element “meta”.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “marginheight” attribute on the “iframe” element is obsolete. Use CSS instead.
The “marginwidth” attribute on the “iframe” element is obsolete. Use CSS 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.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
