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.
The “border” attribute is obsolete.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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Errors:
The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.
No space between attributes.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
