Numbermatics.com HTML Check

HTML Validation Tool

Warnings

Consider avoiding viewport values that prevent users from resizing documents.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

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.

This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.

Errors

Attribute “xhref” not allowed on element “link” at this point.

Element “link” is missing required attribute “href”.

Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).

The element “a” must not appear as a descendant of the “button” element.

Bad value “https://twitter.com/intent/tweet?text=Numbermatics - the number explorer&url=https%3A%2F%2Fnumbermatics.com%2F&via=numbermatics” for attribute “href” on element “a”: Illegal character in query: space is not allowed.
