(Rescan now...)
Errors:
Bad value “navigation” for attribute “role” on element “header”.
The element “button” must not appear as a descendant of the “a” element.
Attribute “viewport” not allowed on element “svg” at this point.
Stray start tag “img”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Stray start tag “span”.
Stray end tag “span”.
Attribute “type” not allowed on element “iframe” at this point.
Bad value “” for attribute “src” on element “iframe”: Must be non-empty.
The “scrolling” attribute on the “iframe” element is obsolete.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The “frameborder” attribute on the “iframe” element is obsolete.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 “aria-controls” attribute must point to an element in the same document.
Warnings:
Unsupported SVG version specified. This validator only supports SVG 1.1. The recommended way to suppress this warning is to remove the “version” attribute altogether.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
