Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Errors:
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Attribute “lt” not allowed on element “img” at this point.
Element “script” must not have attribute “async” unless attribute “src” is also specified or unless attribute “type” is specified with value “module”.
