HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
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.
The first occurrence of ID “section5” was here.
Errors:
Bad value “” for attribute “id” on element “section”: An ID must not be the empty string.
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “section5”.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
