HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
Empty heading.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “contentinfo” role is unnecessary for element “footer”.
The “border” attribute is obsolete.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).
Errors:
Attribute “webkitallowfullscreen” not allowed on element “iframe” at this point.
Attribute “mozallowfullscreen” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete.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.
