HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
No space between attributes.
Bad value “Submit” for attribute “lang” on element “input”: The language subtag “submit” is not a valid IANA language part of a language tag.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
