Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Stray end tag “div”.
Attribute “mobile-popup-open” not allowed on element “a” at this point.

Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

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).
