Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Potentially bad value “allow-same-origin allow-scripts allow-popups” for attribute “sandbox” on element “iframe”: Setting both “allow-scripts” and “allow-same-origin” is not recommended, because it effectively enables an embedded page to break out of all sandboxing.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “form” role is unnecessary for element “form”.
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “type” not allowed on element “div” at this point.
Attribute “value” not allowed on element “div” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The element “iframe” must not appear as a descendant of the “a” element.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “allowtransparency” attribute on the “iframe” element is obsolete. Use CSS instead.
Attribute “href” not allowed on element “li” at this point.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Saw a “form” start tag, but there was already an active “form” element. Nested forms are not allowed. Ignoring the tag.
