Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “icon shortcut” for attribute “rel” on element “link”: If the “shortcut” keyword is present, the “rel” attribute's entire value must be “shortcut icon”.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
Attribute “placeholder” not allowed on element “input” at this point.
Attribute “placeholder” is only allowed when the input type is “email”, “number”, “password”, “search”, “tel”, “text”, or “url”.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value “tel:(646) 564-5601” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
Element “ul” not allowed as child of element “ul” 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.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
